No Engineer category for the trickjump contest ?
All classes are allowed in the co-op contest. There is the solo contest, which has 2 different sections (demo and soldier) and the co-op, which is basically do anything you want, within reason obviously.
Are there any weapon restrictions for trick jumping?
No. Do anything you want as long as it's reasonable (for example, don't modify weapon stats or use plugins to give a medic a rocket launcher)
I added these in addition to adding
NO BHOP to the trickjump rules
Also fixed stuff with the email, so if you for some reason already sent in a trickjump, you should resend it.
