The best way to get in contact with us is to join our forums and make a post in the appropriate section.
If you feel more like talking than typing, connect to our Mumble server. You'll usually find a lot of us hanging around there.
Or you could join our IRC channel #specialattack on Quakenet. Use our web-client if you don't have mIRC installed.
Alternatively you could send us an email at email@example.com.
