sig question
 

I tried to add text to my sig, but it said I had too many lines.

What am I doing wrong?

The site prevents people from having signature larger than 200 pixels high. If your signature is close to that limit, then you cannot add to it as the site will actively refuse the change.

Also, the pic in your sig counts as one line, so if you try to add text under it or over it, that is considered a second line and not allowed by the site. If you're trying to add the text next to the pic, then it's probably an issue with the 200 pixel limit, like Joe said.
