How would one go about deleting their account? Can't seem to find that button.

You cant.

I think there should be a way to delete old unfinished drawings. It would save bandwidth too, right?

If the drawing is still set to unfinished in your gallery, you can set it to finished and then the delete option will reappear when you go to the edit/delete link for that drawing.

bandwidth is only used if someone looks at the drawing. I will tell you now the disadvantage of deleting work far outweighs the space/bandwidth advantages. If you're looking from a cost perspective, I might as well just shut down the whole site.

That's not a bad idea there, Marcy.

yes it is
