You could ask me!!! And there are plenty of good tutorials on-line. Try downloading a 30 day trial of photoshop. See how that works out for you, and if you like makings sigs, then you can buy a cheaper, 'watered down' version of photoshop. I recommend downloading the cs2 trial. And if you want to buy photoshop, I recommend you buy elements 4.0, as it's very simple to use. KK. Oh, also, sig size limits are width of 540 pixels, and a height of 150 pixels.
