How do you keep the signatures you make of a good quality? I have a terrible time with it, especially with fonts. They get fuzzy and finally almost boxy by the time I finally get them under the file size limit. (I use Adoe Photoshop 5.0.)
See where the quality button is, under that you can blur the picture slightly which gets rid of the pixelated look (it may look different on 5.0 than CS versions but it will be in there somewhere)
