I thank when a post is usefull most of the time. I prefer to do it most when someone gives valuable feedback (screens of bugs, comment on the gameplay problems - both compliments or complaints) as thats are the most usefull posts to mappers. Jokes are fine but i only thank them when they are at the right moment. I would never thank a post even if its a welcome bump but the post doesnt make sense or ask something that shouldnt be asked. A good bump however will be thanked by me.
Too bad l4d2 misses sich button ingame... i would have loved to use it in survival.... T(H)AAAAAAAANKS
