I've got it working as such using Regex...
Placed in inc_header.asp
if Application(strCookieURL & "down") then
if not Instr(strScriptName,"admin_") > 0 then
This increases the size of the text at the top of the forum (menu), the date info on posts, and also the titles and post content
It's still in the testing stages though so any feedback would be appreciated
