Hmmmmm Just noticed that when an admin or moderator edits a post, it removes the original posters signature, or if include signature is turned on it puts the admins or mods sig in instead.
it won't put the admin's or moderator's signature in someone else's post. All that checkbox does is toggle whether there should be a signature or not. The signature is retrieved from the Topic Author's (or Reply Author's) profile when the post is displayed. Whether or not there is a signature associated with a post is dependent on whether the Admin or Moderator actually checks or unchecks it. (which may be the case)
In other words, if a person has included their signature and then an Admin or Moderator edits that post, for the signature to not be included, the Admin or Moderator would have to clear the checkbox.
(as a test, I have edited your above post, your signature is still showing)
ok thanks, ahh i see what happened my sig came up in the preview before I posted, but your right it doesnt actually post the admins/mods sig only shows up in preveiw.
