I quit making sigs years ago. All you need is Photoshop (or GIMP). www.planetrenders.net/forums has everything from tutorials to renders. You can also find stocks, C4Ds, Brushes, Fonts, etc.
i think i got it lol XD but i got it from someone else on yahoo but other then that i downloaded gimp and it pretty ok but consumes time and don't find the time right now. Thanks though jimwhat
