Hey Cooler, there seem to be a lot of members where some have either never posted on the forums and/or haven't used the site for over a year. How about sending them an Email asking if they are still interested in the site and deleting those who aren't or who don't reply? When you are searching through the names for someone you go through a lot before you find the one you're after. Just a thought.
The reason we don't delete members is that you never know when they might just have something to say or wander back to the site and alot just browse the site and membership allows them to keep a cookie telling them when they last visited and which messages are new.
I was a member for a long time and never checked the site, then a rather...interesting discussion about CKD came up and I got a message asking me to take part, since when I've spent a fair amount of time.
