Trying to figure something out

[JGM007]

So I have been messing around a little, I am still fairly new to VB3 and very used to VB2 and what I am trying to do is add an extra icon for a different messanger not currently in the message board.
I started out by doing a template search for ICQ and basically copied the statements and renamed them accordingly. It was a long shot in the dark and it did not work.
Are there any php files where this data is hardcoded in? I did not seem to find anything in the database itself that would indicate it would need any changes.

Also how would I make it so when you click on it, it goes to a URL/username, I am guessing somewhere tack in a variable http://URL/$messanger_username but where?

Anyone have any pointers on what I should try to accomplish this?
