Thank you! I've switched to the Sapphire theme, which I'm not quite as happy with but it seems to be the best for my needs in general. Unless I've missed something and you can figure out a way of getting this excerpt function working in the Regulus theme?
While I'm being a pest of a newbie and bothering you with questions, is there any way to change the date on posts? I've been copying in and cutting up a ludicrously long article I originally wrote on my LJ, and with one thing and another I somehow ended up putting up the sections out of order. It doesn't matter so much when you go straight from the main page, as I link to them all in the correct order there, but when you read the posts individually they link to the ones before and after them (one thing I do like about Sapphire), and I'd like that to be correct. It's only one post out of order, but it's the one that goes right at the start.
Also, I'm rather startled to see posts by other bloggers being randomly linked to at the bottom of mine. Is this something that happens with some themes but not others, and how can I stop it?
