You should try getting on now when you have the time. We've stopped linking people to mibbit (which is what was causing so many technical issues for people in the past) to a new web client which is much cleaner, prettier, and most importantly, much MUCH more technically reliable. It's called
KiwiIRC -- just put in "#runouw,#main" for the channels or add them to the end of the link if you're bookmarking it (sorry, [url] tag was being weird). Hopefully, if we get more people to try to get online more often, there will be more of a chance that the chat won't actually be dead (and it usually isn't, honestly...maybe you were just coming online at a weird time like when everyone is at school/work for some reason, or if people were playing a game or something. You're in the UK, right? There are plenty of regulars from timezones around there.). Alternatively, there's the CyTube for which there's a thread in Off-Topic somewhere (honestly can't really be bothered to look for it right now but the link is
http://cytu.be/r/runouw I think), but for the most part, that's just a backup chat or something we use when we want to watch videos or listen to music together.
