Group are very handful, certainly for big rp's (if the group glitch would be gone XD)
but sometimes, the leader isn't online ... and members want to join. or then you have the problem
of living in different timezone, so that you need to try for 2 weeks to finally get into the group ...
maybe it's an idea to give some people a higher rank in the group, as co-founder or something like that.
they also have the option to add people to the group, but maybe not the option to delete them ...
it would be a handful option for people that made a group together. then they can control it both, in stead of one person ...
