I have been in and out of a lot of different groups. I've been asked to admin some too, but then that seemed to be a problem. I saw this one group owner really get upset with people not participating and not sure what she was expecting, because people WERE participating. I run one group of my own which is small and geared towards dogs & cats only. I have a handful that participate & I throw something out there from time to time. I don't pressure people to participate and I don't put a lot of pressure on myself to post either. I find the bigger a group, the more stressful it is to manage. There are a kazillion groups out there and people all have their own lives. I certainly would not take it to heart if people aren't active. I'm sure you've asked for input from your group members?
