Well, since I’ve never heard of a W.I.E., I don’t know what you are talking about. I looked at your site and the font sizes for everything look normal.
See: http://codex.wordpress.org/I_Make_Changes_and_Nothing_Happens
and http://codex.wordpress.org/Playing_With_Fonts
W.I.E. online is the thing on the top of the sidebar, where you see the little square with the green eye. It tells me who is online on my site. I get a general script to put on my site after I signed on, but then the names become very big. That’s something I want to change.
B.t.w. I think W.I.E.-online is something Dutch?
Their website: http://www.wieonline.nl/
They you will need to talk to them and see where they put the controls for the fonts. It doesn’t look “big”, it looks, just there. It’s smaller than your link headlines.
Good luck.
