At the moment I’d be more than happy to post as a draft and set the kind myself. I suspect that I’d reply using the WordPress editor, like now, rather than Drummer anyway.

I had previously been maintaining/displaying a separate category structure fo...

I’ve done this, think I might have to read the ‘wp tag cloud’ in the WordPress Codex to make it look a bit nicer.
