Need recommendations for hard-core drag forums:

[C-10 simplex]

Can you think of any hard-core drag forums?

Yellow bullet has closed their registration(?) Can't figure out why?

ClassRacer has rejected my application---because it doesn't meet their "requirements?" (again---???)

If you can figure out how to contact Yellow Bullet without using e-mail to figure out why they aren't accepting new registration, that would be helpful.
