yes, it was my fault.
no, it did no permanent damage (unless you use internet explorer, in which case the hack probably infected you from top to toe with trojans).
anyone who wants the gritty details, let me know, but suffice to say that i should have upgraded this forum years ago. when i find the time this week, i will.
anyway, thanks for the heads-up from porl. and thanks to everyone who fled like rats from a sinking ship

one of the cool things this debacle has taught me, is that it seems my hosts make backups of every database on the site every day. good one, hosts.
