You can find people to play with on public server all the time, however I think most of those are hosted it europe so YMMV. The main problem I have with Warsow is that the greater part of the regular userbase is very experienced and when you try to get into it at first it can be a very... punishing experience.

It's very fast paced and requires quite a lot of skill and muscle memory to become good at it. There are a couple of "noob" servers that are quite enjoyable however. Overall a very good game.
