So I submitted a post and re-read it (as usual) and found a typo (as usual) so I clicked the edit button.

It processed and processed, took a lot longer than usual, and when the edit window displayed, there was a (new?) section at the top with the option to delete a post?????

YAY!! Is this new? Or was I just not seeing it before?
How exciting to have the ability to delete a post!
How long does this option remain available after submitting?

ACK! I just did it again but the delete option was not there! I swore I saw it before. Was I imagining it?

Ugh, I feel silly. I wish I could delete this post now.

Yep, just tried it again. Nothing. Darn.
