Asi: Aye aye cap'n, I'll get right on it! RE: avvie size. I can have 150x150, but I'm not sure now if normal members can... Easy way to find out would be to go onto the avatar editor page on your profile thingy and tell me. It says the maximum size on the Edit Avatar page.
I'll make it 100x100, which is a safe bet - it's the size I've always used for avvies. Also, I have no clue how to make a sparkling border, alas. In the old days, I'd be able to dredge the wonderful tutorial forum on Advent Children.net, but alas the site is no more and all the others I've found are total rubbish. I'll have a shufty around on lj and see if I can dig something up for ya, but if not it'll have to be a plain border. ^_^;;
Set should be up within the week, work depending.
