@johnpears(View Post) It is possible for mods to delete comments. Editing/deleting shouldn't be allowed for normal users because it can be used for things like deleting evidence or framing other users during arguments (also some other not as bad things). If you want your comments deleted just ask a mod.
@Factorial(View Post) That's never going to happen, not even moderators can delete posts, only hide them. Just read some of the reasons i gave in ky last post. Also I prefer locking threads and not deleting them and would be OK if people could do that.
