How do you edit or delete a post that you have made ?

Good question Yogi !!

I'm baffled there's no obvious way to do it.

Settings will need altering to allow that. By default only mods/admin can edit. I'm on my mobile now so its awkward to do as I may spill my beer! Can look at it in the morning as its a simple alteration in the Admin Control Panel.

You should be able to edit posts now.
