ON COMPUTERS

For new-style fun, check out IntoTheMist, ZoomTheater

A friend invited me to a live concert, complete with mystery mansion, at IntoTheMist.net. At first it seemed like a video game, but there was more.

The setting was the Roaring '20s, with jazz bands, bootleggers and flappers. I headed upstairs to the "high roller" area. Suddenly I was in the midst of a Zoom meeting. The chips were flying and the bettors looked attractive. But I ducked out. I prefer family poker.

I followed arrows in a dark hallway, stumbling around until I found myself outside on the virtual street. It was a bit spooky, so I quickly reentered the mansion and found a room with a live actor playing the writer Langston Hughes. He introduced himself and asked my name. The poetry was great, the biographical detail charming. Others soon joined us.

The joint was jumping by the time the live concert began, with 143 people watching the Chicago Cellar Boys play jazz-age tunes. The singer wore her hair short with "shiny bangs," as one participant described them. The texts never stopped flying, mostly from the U.S., but also from Hong Kong. We could see each other, unless the other person had clicked off their webcam. I turned mine off so I could dance.

My friend found a lot more to explore than I did. She went beyond the blackjack table and Langston Hughes rooms to find a magic area, an actor portraying the writer Dorothy Parker and another impersonating Ernest Hemingway, as well as a 1920s quiz, which she won. Then she watched a contortionist in a hidden room, visited a speakeasy, and saw some "face acting." Tickets cost $16.

Alternatively, ZoomTheater.com offers free, live events for more than 2,000 people per audience. Right now they're showing Shakespeare's "The Tempest." Turn on your microphone so they can hear you applaud.

CARICATURE AVATARS

I bought a condo from a broker I found online two years ago. How did I remember his name after all this time? He used a free app called Bitmoji to send me a text a few times a year.

Bitmoji, for Android and iPhone, creates a free caricature for use in email or texts. Just snap a selfie and the app does the rest. It's quite flattering. Even if you're having a bad day, it will make you look younger and more appealing. I chose a girl in glasses with a ponytail and a heart on her T-shirt. I can pop it into a regular text message, or into Gmail, WhatsApp, Instagram and others. I can add words such as "Great!" or "Congratulations!" If I just want to acknowledge receipt of a text, a green check mark can appear with my cartoon. Bitmoji has a stunning variety of options.

If you want to do more, consider these tips from the chief executive officer of Ripl.com, which offers customizable templates for $15 a month. He says:

Send your customers a "love note" by direct message through your social media business profiles. Call them by name, and mention a specific purchase or chat.

Share your customers' stories and testimonials.

You can also celebrate your customers' milestones such as birthdays, anniversaries and big purchases.

FREE WI-FI

If you're wondering which cities offer free Wi-Fi, there's a free app for that. It's called Wefi.

Wefi finds only the safe kinds of free Wi-Fi. What's more, it keeps Wi-Fi turned on in places like home or work. It's off when Wi-Fi is not available.That keeps your phone from heating up as it searches for a signal. Years ago, I couldn't figure out why my phone felt like a piece of hot coal in my pocket. I learned later that it was searching for a connection. When I launched Wefi, it showed me a map with dozens of free Wi-Fi hotspots. And it automatically connected. For example, I entered Target recently and was instantly connected to their Wi-Fi.

But perhaps you won't have the Wefi app installed when you need it most. In that case, go to a major chain, such as McDonald's, Walmart or Home Depot. Then tap "Settings" on your phone, tap "Internet settings," and look for the company's name. Most big stores and restaurants have free Wi-Fi.

READER WARNING

After installing the latest Windows updates, a reader writes: "My icons were larger and half hidden. The start button and task bar were also hidden. I blindly got into settings and changed the display resolution from 1980 by 1080 (which is recommended) to 1600 by 1200, and the screen came back to a workable size. However, I lost two folders of folders and videos. I immediately did a [Windows] recovery and am back to normal again." His lesson: "Think twice before downloading this update."

Wise words indeed. If you're unsure, you can pause automatic updates until Windows gets its act together. Type "Windows update settings" in the search bar in the lower left of your computer screen. Click "Advanced options." Choose "Pause updates" and select a date when you want the updates back. As the man on the phone in the New Yorker cartoon says, "How about never. Is never good for you?"

TURN OFF THE ROUTER

A reader noticed that his Gmail wasn't always alerting him with a ding when an important message came in, or it arrived late. Rebooting the router was all he needed to do.

CNET quotes a Wi-Fi expert as saying that turning the router off and on again solves 90% of problems. That's because the router drivers get "discombobulated" (a scientific term, apparently).
