Josephine, it's been down due to some intruder in there.
That's what Fracnis Steen told us to the other edu.tw.o admins (mose, sylvie & me).
I've requested him a backup of the site, to be able to put it up again in another server, if needed, but got no answer yet... and he doesn't seem to be in the USA, qhere the servir is...
A shame for many of us.
I hope they set the server up soon, or just send the mysql backup of the site as requsted (but no news yet)
