Well, what a waste of time that was.
Twice I tried to create a sketch on there with their clunky buggy whatever it is. Twice, it didn't save when I hit the save button, ending in a blank sketch being posted.
I'd hit save. Nothing.
I'd hit save and close. Nothing.
So I'd hit Close.
A box would appear, asking me to add genre, creative commons, etc and save.
Then it would say "you're navigating away from this page. All changes will be lost.
Leaving a title of sketch with a blank script.
