Nope, I've tried deleting the the html tags for usergroups and tried the normal username instead of musername. The space is still there.
EDIT: Okay I've found it. I had the option "Add Template Name in HTML Comments" turned to 'yes' to be able to debug and work on the forums, so I figured that maybe that caused the space cause nothing else was really causing this. I don't understand why it would add in a space though, but I'm glad I found it.
Thanks for all the help

, I really appreciate it.
