Notice: We are going to start deleting old accounts which have less than 5-10 posts. This is to cut down on dead weight of users who aren't active and who don't post. People can always read posts without being registered.
The number of posts won't be the only criteria. We'll also look at the last login date to identify users who have been inactive for the past two months or so.
If you DO login from time to time but don't post, and your account gets subsequently deleted, please just create a new account instead of making a big deal about it. You can even re-register your old nick, and since you won't have many posts, you shouldn't care much either!
Update: Deleted low post count or seemingly inactive users till registration date of 15th March 2008. If you are an active user and I mistakenly deleted your account I sincerely apologize. Please create a new account in that case, you can reuse your deleted username.
