Delete Option?

I really think the mods/supermods/admins should consider allowing us members to delete our posts/replies in a thread? I mean I know we can edit them but how about the freedom of completely being able to delete them...I can remember at times where i wanted to delete a comment or a post but just had to edit it with something else...am I making sense? Who else thinks we should have a delete option to our posts? In addition I was wondering if it's possible that when you edit a post then any person who quotes your post prior to it getting edited doesnt matter SO if that post by you gets edited then automatically the quote(s) by anyone should be edited in accordance..did you understand that part? Lastly that if you delete a post(if the mods approve) then any person who quoted that post wont have it anymore since its been deleted...
