I don't feel it should be some kind of implied rule that the administrator should have the most posts on the forum, but members of a community should interact with the administrator occasionally. It's sort of like the mayor elections in your town. You want to vote for a mayor you know, one you have personally met normally. The administrators lead the forum, so I feel the members who the administrators lead should have a developed friendship with the administrators. I'm not saying this requires having the most posts, but this does require some posting, some participation, and some contribution. I currently have the most posts on my forum, as I have a bit more than 15,000 posts. My co-administrator is second on the list with around 10,000 posts I believe. It may make statistics misleading to some people, but I for one still think that many posts is normally a good thing if the posts contribute. It shows dedication.
