I am just wondering if my font is too large for the forums, I dont want to get in trouble for it

I can't find anywhere in the rules that there is a maximum font size, so I think you're fine. (On a personal note, even though the size is ok, the font itself is not that easy to read...)

Maybe it would be better to change the font to Arial or Verdana or a similar one. I don't think it's too big, better then a 3 px large font ._.

I have to agree with Efinesse on this. I saw one of your posts earlier while browsing the forums and actually skipped over it because your font is difficult to read.
