Being a moderator sounds fun but, is a lot of work. You'll have people PM'ing you asking you to fix things, and you need to patrol the site to make sure it is clear of trolls and thread jackers.
Been there done that not fun, iono maybe b/c it was a small forum.
I dislike moderating smaller forums because things get too personal. I was on a regional Mazda forum that I helped create. Eventually became too much drama. I also moderated a global Mazda forum and that was much more enjoyable because it was more of a business.
I appreciate this site, it's a good balance of scale and activity. And, we have the best group of members of any forum I've ever participated in.
