i don't think it is an bug - it is ok so
if you are cleaning your database from old postings that are no longer needed, and i made 100 postings until now - and now you are purging many threads with some of my postings in them - i have still made 100 postings until now. That number shows all postings, not the number of posting actually being stored in the database..
hmm..my english sucks *g*
