Never thought about resolution settings before. Mines always 1280x1024 or higher. Just tried it on 1024x768 and apparantly, due to 1 word, it takes up 11 lines. Removed the word. Fixed.
Maybe they should specify a generic resolution that your sig must comply by the rules in. Otherwise you can just keep cranking the resolution up for a longer sig.
Its just personal preference, and I just don't like those little bars. I'm sure there are people that don't like my "plain" sig look, and good for them.
