As everyone will be aware the forum is up and running again and seems to be functioning normally, but if anything goes askew in the next few days then no doubt this will be related to the recent saga.
Luckily the guys who hacked into the site were good enough
not to do any mega-damage, all they did was to (more or less) redirect the forum's frontpage to another site, which showed the message with the black background, and this obscured the forum's frontpage.
So everthing underneath just chugged on more or less as before, but getting rid of the black page was a bit tricky.
