I think there is a new level at 250 but may be wrong. They keep on changing right up to the 1000's but most if not all of the 1000 plus posters are on the design team or are moderators now.
1500 is Auilliary archer I think. Nik just made it before he became a moderator
I notice that Andy has moved from 205 to 209 posts since I first saw his post
If you are interested in post counts you have to watch for the culling of posts after a while to free up space which in at least in some fora is done and reduces post count. I'd hope we are judged on how constructive we are rather than on raw post count
To be honest recent discussions on gnat's equipment asside the content to noise ratio on this forum is very very good. Most of the messages are valid questions or answers and if you use the search facility you can find a lot of good stuff.
As to culling posts that has not had to happen yet....
