Forum 1 usergroup says that the forum text is the same color as the Username HTML Markup
 

We have a few additional user groups, one of which a few members are seeing the post's text color (which should be black) as the same color as the Username HTML Markup (which is gold/orange).

I checked the user account using "login as user" and used their browser of choice (Firefox), and this time noticed that their post are definitely in orange, but the replies are not. IE doesn't show the same issue.
