It's pretty simple to stay alive on Corner Carvers; read the newbie (wiki) guide and follow the rules outlined there, and you'll be fine. If you don't, the moderators will probably give you a good roasting before promptly banning you. It was founded by some guys mostly from Corral.net (Mustang site) but has grown beyond that; there are people there with all kinds of cars. The general discussion forum is a good way to ease into membership there if you've got a decent head about your shoulders, which pretty much everybody from SECCS does.
If you need to post tech questions, just make damn sure you do thorough research and don't ask a Q that's been answered before.
