I'm extremely disappointed with this business solution (cloud version). They abruptly removed a vital feature without offering any viable alternative. This has had a significant negative impact on our workflow, and it feels like they've left us high and dry. It's frustrating when a solution you rely on fails to meet your basic needs and doesn't seem to care about the inconvenience caused. I would caution anyone considering this solution to think twice, as their commitment to customer satisfaction seems questionable at best

Libre selfhosted version is good
We use the free version bundled with gitlab. Great when old IRC generation meets young slack generation. Bugfixes are quick, Android app sucks, webapp rocks. Got laptop sticker when I met them at a fair.

Good and useful program for internal information flow and exchange. Is very useful for us especially in Corona time. Easy to use and super fast to learn. A few more text options would be helpful.

Nicht mehr zeitgemäß
In Zeiten von MS Teams kommt MM leider nicht mehr mit... schade. Die Usability ist einfach nicht mehr zeitgemäß.

Superb chatting tool to monitor the progress of your web work. We would suggest the same for an instant turnaround :)

Great wee app
Great wee app, lets you run your own little chat server outside control of Facebook or slack. Some fidgity things with plugins, etc but understanding considering the scale of the program/development.

Complete waste of time
Downloaded app on android. Opened it and said enter server URL. I did and it asked me to sign in, but I don't have an account and it has not given me ANY option to create an account. Complete waste of time, unable to use it! Not option to fault find or anything.
