if you want to get more technical you could use several freeware programs
paint.net- the easiest UI you could learn
gimp- A little bit complicated then Paint.net but it has more options
sumo paint- It is online. http://www.sumopaint.com/
umm that look like a good one, how to use it as a sig?
And do you mind if you just take the ‘A’ away? no one calls me a virus anymore, just VIRUS is fine, thanks!
For this I just used Gimp. I do my fair share of Photoshopping as well but Gimp works nicely for simple stuff like this and doesn’t suck up a whole lot of system memory.
