I'm new, and am trying to configure a few basic things, and am stuck.

I'm trying to change the basic layout of the way the username is displayed when showing comments. Currently, it shows as this:

[code]
username: comment
[/code]

I just want to change it to

[code]
username
comment
[/code]

I thought it would be simple, but I can't find where in the code that the ":" is being created. Any help?

Also, ideally, it should only do that for the "main comment", not for replies. But I'll take what I can get.
