Hi.
I just registered and noticed some things during the process. Aside from "the successor of battledroids" not being a valid name for this game and "mechjocks" not a proper designation for pilots... ;) :P
1. The captcha is very weak - almost unreadable for humans (had to use 'listen to the letters'), but with the low amount of transformation applied to the letters, easily readable for machines. Why not use something more modern like e.g. recaptcha?
2. I'm using googlemail and the registration mail ended up labeled as spam. If you'd be running your own mailserver, I'd tell you to look into the config of that, but since you're using gmail too, you probably can only sit and wait until googles mail filter learns that the forum registration mails are not spam.
On a slightly related note, it would be nice if the password requirements (small & large letters & digits) would be listed somewhere on the registration page.
