Sorry, guys if you're having problems registering. We have insanely tight registration requirements to keep spam at bay. And yes the contact feature is only for members, sorry.
FYI, we get about 500 attempted spam registration every day. Sometimes 50+ a minute.
Try the below and if they don't work then PM me here with your attempted Username email and IP address and I'll look into why your being blocked.
1st off No numbers in the username. Spambots use numbers allot so it was removed as an option.
2nd try disabling your ad blocker or DNS trap. Both can cause issues with the Human Verification system.
3rd clear your cache and try again. This should actually be the 1st thing you try.
4th If you were denied more then 10 times the system will block your IP for 30 days. I know that's rough but again the spambots are to blame.
5th About a week ago I changed the physical location of the registration code to again try and block spammers. Try again and see if it works now.
Lastly, the only other thing I think of is the reCaptia server may have been down while you tried to register. I just checked it and it appears to be working now.
Again if you're still getting blocked message me here and I'll look into it.
