I believe that since this is an art community we should be given more flexibility in the file types we can upload. Because a vector file usually doesn't look as good when made into a jpg or gif. And it will make life a little easier by not having to convert psd or ai files into other file formats. On deviant you can do this. I don't know if u guys are still working on this or maybe it just takes up too much space but it is just a suggestion.
