Those regular participants who moderate a group have been given new comment editing powers. This applies to all comments posted on the web site. It is for the purpose of moderating comments and should be used sparingly.

You will notice a "delete" and "edit" tab below the posted comment.

Delete:
If you delete a comment any comments attached as a reply to this comment will also be deleted. It is preferable to make the comment invisible. (see below)

Edit:
With edit you can open a comment and remove a line or revise. If this is done to the comment of another hopefully you will contact them and explain why or post an explanation.

Invisible:
You can make a comment invisible by selecting "Edit" and then "Administration". Then check "Not published". The comment will become invisible as long as it remains at this setting to everyone except other editors. The editors will see it colored pink to indicate it is invisible.

By making a comment invisible it will remove it without deleting any other comments attached as a reply to this comment. By checking "published" the comment will become visible again.
