Well, there is now )
Actually that's not quite true, it's essentially IRC, but on a newer more feature full platform http://matrix.org
There are clients for browser, IOS, Android, and a few up and comming desktop clients also.
Oh, and there is a plugin for the Weechat IRC client users also.
Enough of that though, here are some links....
- #onion_omega:matrix.org client selector This link will take you to a page with instructions on connecting via various clients
- #onion_omega:matrix.org web app This link will take you to a page allowing selection of a client then send you to the room.
For IOS and Andriod, first visit the riot.im home page where you will find links to the available apps in their respective stores.
Once you have installed an app, you can use the client selector link to connect directly to the room.
Riot also offers an electron web app for Linux, Mac, and Windows if you would rather not run it directly in your browser.
Once you have connected (via whatever client) you will need to create an account to access the room as guest access is disabled to help control spamming and abuse.
I'm present there as dcg_mx, I can't promise I can answer all of your questions, but as the room membership grows someone will be able to.
See you there.
