My current group has not run a Rogue trader game for a while due to absence of GM and i'm looking for a new group. I have ventrilo so that is no problem.

You could try http://www.rpol.net/ It is online pbem gaming. I know there are at least two RT campaigns there.

i tried there, i made an account but becuse they use tracking cookies i can't seem to log on.

Dark Reign has some online games you could apply for.
