Why is it that the button to Edit/Delete posts only allows you to edit the post and not delete it? I think a post delete feature for Members would be GREAT. Seriously, you should consider it Webmaster. I've been on plenty of fourms that allow that option and it really comes in handy.
There was a problem a while back where a small group of members in good standing got pissed off at another small group of members in good standing. One group decided to leave and wanted me to remove all their posts -- and the posts of others who had quoted them. Doing this would have caused a disruption by making some threads unintelligible, so I declined, but they still had the option to do this themselves (one by one) and some attempted to do exactly that. After that incident I disabled the option. I no longer delete long term members in good standing because someone can assume their identity immediately after they are removed. Instead, I'll just disable their accounts and eventually their posts and their screen name will be deleted over time as old posts are archived or removed. If someone wants one or more of their posts removed, they can use the "!" option -- which people have done for various reasons (duplicate posts, change of heart, etc.).
