So. Quite by accident I found it!

Under 'Spaces,' click on the gear next to the 'Space' you want to edit, and select 'Customize…'

Now as soon as it shows you the wonderful themes you can select, click cancel. Yes, cancel. We don't want to edit the theme, we want to manage posts and that's why we've come here!

Once you cancel, be very careful - you're now on a page that allows you to edit and mess with posts from the past (and I'm guessing drafts and such) all in one place. But don't click on a tab at the top, because you'll never get back here again without feigning that you want to customize your theme.

That's right, it's easy as pie to get to a feature you use maybe, um, once a month if your fiddley, once *ever* for most, I imagine, but to get to a feature many probably use every day it is:

• not intuitive where it is located
• eclipsed by other features of questionable usability
• I don't think it's even supposed to be there…

Honestly, I was expecting all that stuff to be lodged squarely under 'Activity…' but apparently I don't follow anybody (or maybe all the dozens of people I do follow aren't going for this social shit right yet) but that tab is useless.

*sigh*
