It was quite fun, I'll sure try to come to more of these trainings. I could only stay for a few rounds when we moved to the public servers since it was already past midnight here. Speaking of which, maybe we could move it 1 hour earlier so people who wake up in the morning can attend the full training? If the organisers can do it, you could make a poll to see which time is preferred by the majority.
As for the server side, I suggest we use CTF from the start for future trainings, it has no bugs and it's a lot more stable then deathmatch. Can't do anything about the lag, unless you live in Eastern Europe pings will be higher then on the official servers.
