I periodically edit posts and correct simple things like spelling, vB codes, inoperative links, etc as part of my moderating chores. It dawned on me today that some posters may not be aware of the fact:
Any member can “edit” his or her own posts. If you post a message and discover a need to correct spelling, add a picture attachment, change the general content of the post, etc, etc simply click the “Edit” button at the bottom of your post, make the changes desired and click “Save Changes”.
