- Buy Photoshop (Or get a cracked version but this isn't really the place to talk about that)
- Get some brushes, render, backgrounds, pattern, C4Ds all kinda'f useful stuff
- Play around with Photoshop a little bit
- Take a few tutorials (Google them)
- Then just use you learned and what you figured out and make a "Cool Sig"
I recommend Photohop aver Gimp cause I use it but if you didn't find a cracked version then just get Gimp (I think it's free)
Most of the goods ones are made with Photoshop, which if you don't have it or cant afford it just ask in the GFX requests sections and someone will make one for you. Also, what are you looking for in a sig? I have nothing to do right now and could try and make you one, or my buddy houssem above me could make you one as well he has some Photoshop talent, or many other people. I need to create a new sig and avatar for myself for NB now that I am using Photoshop, these are my old ones from before I got banned and I didn't start making them until after NB banned me.
