You aren't signed up on the RvS Coop ladder but would like to submit your scores as well? No problem, as long as your clan is registered at the *DBL with all its players. Just drop us a line in the RvS Coop Ladder FAQ until 23rd december:

Admins will add you to the RvS Coop ladder.
Btw maybe my late night RvS Coop rule post wasn't very clear, in short:
Play the coop missions posted below with adversial game settings and take an ingame screenshot of the success message together with the time that is left and submit the time in the *DBL forum.
Good luck and happy hunting!
