I'm in a lot of groups but I make a wide range of art and crafts. Depending on what I'm making at the moment will cause me to be more active in certain types of groups. Am I doing more spooky dolls or more altered art books for instance. I don't stay in groups that I'm not active in. I do have several that I watch because they are great, but I'm not in. I have their group stamps in a seperate section on my profile to help send traffic their way.
