Creating a user or usergroup only custom bbcode.

[Darat]

In a forum I'm admin of we use a table created via a custom BB code to make an edit in a user’s post. The mod would type in something like



[ mod=me ] This is the reason the post was edited. [ /mod ]



This is then displayed as a table in the post.

It's a useful tool but of course any user of the forum can just type in the [ mod= ] [ /mod] BB Code and whilst we've only had a couple of abuses of this I was wondering if there is someway of making the bb Code only work for someone in the Moderators usergroup?

Any ideas or is there a better way of achieving this? (For vBulletin 3.03.)

Thanks.
