It's easy. Just delete the background nodes and viola transparent image:)
It's not that easy as apparently the vectormagic website sees things that I do not... blocks and sh*t that's transparent in the PNG... I used imagemagick to convert but that was way worse, however as a test I converted the PNG to JPG and I see the issue... (blocks of non-transparent layers)
As far as the transparency thing.. it blows that you have to pay over 200 bucks to have that program do it for you.. I have been unable to find a program (as a non-graphical artist) that does this conversion as well, however.. If you have a crew of 20 or more, get donations and you're in for about 10 bucks a person... easy... otherwise you have to find a clan color that you can then add as your outline... as I did.
I can make the background transparent for you. I've requested an invite to your crew. Once you accept that I'll edit the emblem and save it as a new one.
I added you. PM me if you need the source PNG file (though it's also in this thread)
