Uknow, this one sometime back. I downloaded the RC5 program and started some cracking. Then when it was time for me to join a team, Anands team, It wouldn't let me??? You think it would do the same now? I might just join if I can get on the team, I hate to crack a whole bunch of blocks like that last time and not be able to join again.
[EDIT]: I remember why, it wouldn't give me a password or passcode to join a team, it was taking forever, so I gave up.
