This group is open to all! Almost.
Too many times, I have been checking out some really amazing sprites here on dA, and I scroll down to see a rather unattractive stop sign with some sort of egotistical rant about how the author's sprites are some sort of amazing work of art that you can see, but not touch. That's kind of absurd. Especially when they couple it by responding rudely to usage requests, with things like "Sprite your own," which sucks for people who are just plain awful at spriting.
And so, this group was born.
The only requirement we have for submission is that you allow your sprite to be used freely by anyone, without permission.
IF YOU DO NOT WANT PEOPLE TO USE YOUR WORK, DO NOT BOTHER SUBMITTING.
As of right now, there is no daily limit to the number of submissions that can be made, but this may change as the group grows.
In addition, right now, there is no approval process for sprites, but if they are not all of the following:
1a) Pixel art
2b) A drawing or rendering
2) Pokemon Style
3) Not simply a re-colour of an official sprite
4) Allowed for general use
...they will be removed from the group.
Happy Spritin' and Hacking!
