Heya dude, just letting you know that your sig might be too big for the rules. Mine was, and I reduced it to 500pixels wide using
Fotoflexer as its real easy and quick if you dont have the right software.
You can check if its too large by downloading it then looking at its properties, or by going to its direct link (the page with just the pic on, you should be able to get there from your photobucket/imageshack account).
If its more than 500 px wide it needs to be reduced.
