i've found that when I msg the leader with: "do you mind giving leader or assist so i can put my team in the same group please? =)" it works about 80% of the time.

I've got another problem tho - when I've actually got raid leader, how do I move players into the same group when the raid is full? I'll end up with 3/4 in the same group but can't move anyone in or out after the raid is full. Anyone mind sharing?
