In EU for a few weeks, want to play

I've been playing for a few years in South Africa, only on local servers (well, there is only one), since we ping 270+ to EU. I'm in England at the moment (I'm English) for maybe three more weeks. I've been playing pub a lot, and I merced in some random 3on3's I found on IRC, but those are hard to find (nobody wants to take a "random" player). I'm keen for playing 1on1, 2on2, 3on3 or 6on6 matches. Any suggestions about what I should do, given that I have a limited amount of time (i.e. trying to join a team for three weeks is probably fail)? Mixes are fine, don't know where to start though.
