I'm using Discord these days, and plan on using it for my RP channels going forward. Why? The requirement to be invited to servers, for one. For another, I can't run my own IRC server yet, and I want more control over my chats.
Also, I'm on Telegram as well, but only because 1) I have a "burner" number, and 2) most people I know refuse to use XMPP.
So yeah... Send me a note, or email me at (please include information about who you are), if you want my user info.
