Hmm, strange. Livejournal is quite happily sending me comment notifications and so forth to the address I have registered with them, however messages to firstname.lastname@example.org which are forwarded to the same address are not getting through at the moment: with it complaining that the mail server isn't saying anything quickly enough. Despite it being the same mail server. I've no idea what it's doing differently when forwarding mail that would cause problems.
Anyway, in the meantime I recommend mailing me as eleanorb at either chiark or gmail if you want to get in touch. In fact I'd recommend those most of the time anyway!
