remember the last editor you used. So if you accidentally used the RTE
(e.g. because of doing SB photo posting) and want to use the plain text,
you may want to go to http://www.livejournal.com/settings/?tag=editor
and set it to always default to plain text so you can get back to it.
Unfortunatly, your SB posts will still start off in rich text but you
can't have everything.
