The total number of posts is so low on my list of priorities that I think you should forget about it. It is not relevant and proves nothing. 2,000 posts with nothing but inane drivel are not worth one post which is interesting and informative. Please stop going on about the number of posts.
If I can twek the system to ignore or not show the number of posts then I will but as I said, very low on the list of priorities. You have a working forum so please make use of it.
