It's kind of hard to read run on sentences when you're high.
Anyway, the thing where people leave the server after map change? I've seen that happen on biotec, shreddingfield, even on armory, coming from snuggles with like 10 players, and so on. It can happen anywhere. The end of a map is just a convinient place to leave the game, or rage if you rather not play the next map. Etc.
Sure, sometimes the map deters them from continuing, but where some players really like maps, other players really hate them. The server doesn't stay full after you change to any given map, usually, someone will leave, one to three on average I'd say. Five or more and it's a kind of a problem, but you'll get over it, and if it's like eight or more, it's time to RTV again.
Yeah, the adding people thing is really the key, it keeps it kind of personal and makes people you've added feel more inclined to come play again, rather than forgetting about the experience on our server completely and never returning.
Meh, if they rather play somewhere else than help start our server up, to hell with them! Not really, but rawr. It'd be nice if they tried to help us out..
