So for doing races and just random chatting on SpeedRunsLive, I have created a channel on their IRC server, just because IRC is the easiest chatting service to join and SRL can be used for races, which are created in #speedrunslive.
http://www.speedrunslive.com/faq/#join A guide to create an account for SRL and get on the channel. The channel name is #trialsgames (cause just #trials would maybe be used by SRL or for other purposes, idk). Join that and I should be in that channel most of the time. Again, since this is IRC, don't expect a reply immediately, unless you tag me with my name, where I would get notified, if I'm at my PC, a reply would quickly appear. I use Hexchat as an IRC client, a very good client for basic stuff and it's completely free, doesn't use any system resources.
