I know how you feel, my site went down for over 80 hours because my host was a big piece of shit, and now ive lost all the sites i submitted, once a day. Not alot on greenguy, maybe 15-20, but other linklists had over 100 of my sites listed which have now been taken down because of the downtime i had.
i feel your pain
It would be cool if 404/down sites were just put in a que, and check each day, and if they come back up they are added in again. but thats not likely to happen
ahh well, tomorrow ill start resubmitting 1 by 1 i guess
im just glad i switched hosts and will have something more reliable (my good friend runs my new hosting)
