Forum font keeps getting smaller

[spidey07]

It's at what looks like a 4 point font right now. I looked everywhere in options but it's almost unreadable it's so small.

So what am I doing wrong? Firefox 3.5.7

-edit-
never mind, figured it out. CTRL- or CTRL+ changes it.

Oddly, I thought it would be a smart ass reply to tell you to use ctrl + or -
