If you click 'manage submissions' doesn't it let you click them all to delete? It's a bit of a faff, mind you...

You've to use the "invert selection" to check all. I already posted this "trouble ticket" in the forum.

Yeah, it'd be cool if they fixed up their submission notification stuff. It makes no sense. <_<

I agree, it is a little strange that you have to go through an extra step with the pic-based submissions/collections and it did take me a bit to get used to said extra step.

Needs an option to display full thumbnails instead of a cropped section too.

This exact reason is why I hate using this site.
