I'm not sure I fully understand the question.
If your asking about a specific url to PM killerbee then you can hide it in bbcode for example:
PM Killerbee
|
Code:
|
[url=http://www.nukemods.com/modules.php?name=Private_Messages&file=index&mode=post&u=9196][b][color=red]PM Killerbee[/color][/b][/url] |
Is this what you mean or am I missing the point?
