"sick and tired of seeing on fan forums signatures that are literally an A4 page long just to read a post like
"lol""
Me too - I go to a few other forums and it just plain sucks seeing the same photo of their favourite celebrity or whatever over and over and it takes the whole height and width of the screen!
As for the sig, make it not as high PLEASE 100-120 pixels high should be plenty - also I now you siad you were colourblind but honestly that blue writing clashes so much I can hardly read it - use a light brown or orange maybe
Or failing that do it in white as a layer and blend it on 50% - then it will ALWAYS match whatever colour is underneath without you having to worry about it
[edit] except white, for all you smart-asses going to correct me
