Footnotes? & other LJ stuff

I have this vague memory of seeing footnotes used in some LJ entries. Yet I couldn't find any info about this anywhere just now, when looking at the FAQ. Help?

Also, I received a virtual gift a few days ago. Thanks! (And also: thanks to people who've given me virtual gifts previously.) - I'd reciprocate, but I'm not quite sure if I trust LJ enough these days to give them my credit card data. But, errm, your gesture is appreciated, nevertheless. *sheepish*

BTW

The MAD Doctrine

is done. I think.

(Waiting for the final ok for the revised version. Got a good feeling, though.)

That's why I need the info about how to make footnotes around here. There's a couple of places where that fic needs footnotes.

...

My first "proper" Life on Mars fic! And it only took five years, lol! (Yep, five not six - I found the earliest version and it's from March 2007.) So excited!!!!

Years ago I promised Loz I'd muster the courage to read her stuff once I'd published my first real LoM fic. Guess I'll have to do that now. OH THE HARDSHIP. (Part of me's still scared. But part of me also wants to go for a good long archive trawl in that fandom now.) - Speaking of archives... I've neglected the archive terribly, for years and years and years... another one of the constant sources of guilt in my life. I'm officially still an admin, completely undeservedly. Not something I can remedy right now, what with my life being entirely in limbo at the moment, but definitely something that's not forgotten. One of the things I need to find a space for in my life.
