staff edit BBCODE help

[nick682]

I'm trying to make a BBCODE for my staff so that it displays who edited the thread and why.

I want it to look something like this:

//edited by nick682: wrong section, no swearing,...

Where the username is I want that to be dynamic. So which ever mod edits the post it will display his/her username.

So I would want the BBCODE to display:
//edited by nick682:
and in between the
"[mod][mod]"
you would type the reason post was edited.

--------------- Added [DATE]1272475236[/DATE] at [TIME]1272475236[/TIME] ---------------

I could make a custom BBCODE for each staff member that has their username in there, but I'd really like to make it dynamic so I only have 1 BBCODE for it. Is this even possible?
