You're setting the bar so high with finding "more mature" players in the games you listed with a statement like that. First, if I was an admin from CS:S I'd feel really insulted right now. There's never a need to bash any division or say that the admins are immature, they earned that position because of their maturity. Second, this isn't a thread to bash people or divisions its about a need for more admins to be on in the early hours of the morning to handle situations that come up to keep our servers punk free.
To the OP its been said here already but add admins to your friends list, look around on vent, or use the shout box to get an admin's attention. I've noticed that most people, whether they play the games or not, have a lot of the games eGO supports and are more than willing to help out when needed.
