you can open one up in the fan creations forum for your own personal work. I'm sure everyone would enjoy it.
btw, what do people think of the sig i have right now? it's just a simple rough one i decided to make for myself. I kinda like the filter i used on it, I'm not sure why, it just gives it a certian look.
Spoiler for first sig:
I remember WAY back when TechTV was still around, I entered (and won) their first ever Anime Unleashed Sig contest. I'll dig it up real quick XP
this was my first signature ever. I made it when i was 14, and had no prior knowledge on photoshop, so it was quite the experiment.
I don't make sigs, but i wonder how well i would do. I can't do anything like those amazing looking rendered backgrounds people do, but i can blend images and effects to make interesting things. I did have an experimental image i was working on to make things look like it was incased in ice, but i lost the PSD to it and i've all but forgotten how to do it.
