+1Two suggestions, though. I'd put the server name to a more obvious part of the main post, I had trouble finding it at first. You could even link it with that maniaplanet:// protocol thing. (Don't ask me how it works though, I have no idea ) Secondly, you might want to specify some times of the week (e.g. 8 pm on Wednesdays) when people should come and play regularly. It might not be needed, but I think it would do good. (People rarely join servers with 0-1 people in them unless they have an explicit reason to do so at that moment.)
I think it's should be every evening at 9 pm !
