Rolling up the path...
Sorry, I haven't any better suggestions for you - just sympathy on the situation of having a new email and no record of the old password! This has sure happened to me. :/
Do let us know, please, what happens regarding getting back into FFN. There will probably be other people who realize they'd rather not be on FFN if it means being bot-bait.
OTOH, FFN may have fixed this, yes? 'Cos certainly they wouldn't want a whole bunch of stories coming down over this. Readers wouldn't like that either!
Meanwhile, I hope you have the stories archived somewhere else! So you can put them back up on the OTW archive this fall, nom nom nom. Reportedly, OTW's spankin' new-fangled architecture will make the archive ripe for fan reading, not for commercial plucking.
