@height8 Blurb deletion is possible, involves a teensy but of guesswork.

If it was as the very last post you made it's trivial to delete. Otherwise a bit of a lottery, there are no other clues.
Bearing in mind I'm doing this on my phone; refreshing the Blurb, Podcast & Post list increases the displayed time-since posted by hours for each refresh - it adds a frisson* of impossibility too. ;)
Good to see you BTW.
