for people like administrators on the online list and posts their name is slanted..how do i remove the slant
ACP -> Users & Groups -> Groups -> Administrators -> Username Style
Simply delete the <em> and </em> from the textbox to get rid of the slant (italic to be specific).
In the usergroup settings, you'll see a section to give a style to the username. I think the tag used for italics is <em> and </em>. Just remove that.
