Discord

The Discord client dosen’t work but some features can still be accessed by an updated web browser.

Only Chromium variants such as 360EE or MiniChrome works well. Mypal and Firefox variants don't seems to work.

Ripcord works on Vista and above.

purple-discord for Pidgin 2.14 may be an option for XP users. The only tester of this has been deemed an unreliable source of information so this cannot be verified.
