I'm just curios now, no need for bashing.
This forum have about 4561 members with more than 0 posts and about 19'844 members with 0 post.
What is the gain in keeping all the 0posters?
Why to keep them:
* Takes time to remove them.
* Is against some moral forum rule to remove them.
Why not to keep it:
* Takes more space to store the DB.
* Slower DB queries.
* Harder to browse member names.
* Greater chance your nick is already taken.
* Better shows how many actual member this forum have.
Any more arguments? I'm curious for this in other forums too.
