Ever got annoyed at having to run like 9 different programs for all your messaging apps? say no more!
Pidgin is an open source messaging application that lets you log in to IRC, MSN, Google Talk, Steam, Pidgin, and many more, all at once in a single program!

It comes with many clients by default but for steam and pidgin you have to download the plugins manually
Steam plugin
Discord plugin (available on ubuntu repositories)
Edit: Ok i was excited bcuz i didnt know this was possible but apparently its really barebones
It doesn't support voice chat, embeds, uploading images, hiding channels, or pretty much anything besides basic chatting, but hey its an option
