HELP! My Groups won't stick!

Hi!
New to the group and, new to Peer Trainer.
I hope that you get this as I keep getting kicked out of the groups I join.
I'm not doing anything wrong as far as usage policies go. I've just found that when I sign on to add to my log, I'm missing my groups! The last group I joined went from 3 members to just me alone - over the weekend!
Being that I do so much skimming through to find groups that are relevant to me - finding that the group is missing once I come back is becoming very frustrating!
Can you help to tell me what I'm doing wrong?
Anyone?
