Here is the situtation:
I looked at the list of members - to find "me self" in da list.
I found me, but also found some very usefull data related to maintenance of the forums.
I looked at how many posts users have.
And come up with these numbers:
0 posts = 5007 users;
1 post = 3091 users;
2 posts = 2044 users;
3 posts = 1008 users;
...
( you guess I did this over the browser not with mysql group by function
So just to ask - have you ever though of deleting those users that havent posted anything for let's say 1 year, and have less than 5 posts.
I know that your (user) statistics would suffer greatly, but it would leave only those that are somewhat active on the forum.
What's your "official"
