when hacking like this happens, it's usually when someone discovers a hole in the code, and then everyone who gets told about it try's to hack all sites running that version of the forum software. It happened with the forum software we are using, but back on version 2.0.eleven and all you had to do was change a cookie setting, and you could log in as the main admin! That was fixed ages ago though.
Glas A-S is back up now though, some hard work done by Admin and the hosting people from the look of MatG's post. 20.gif
