I want to thank Nils for sending me an email letting me know that the site had been hacked as I hadn't noticed yet. I don't visit the forums that much at the moment (as I'm kinda taking a break from remote stuff) and even when I do visit, I have the "posts since your last visit" URL bookmarked, so I wouldn't have seen it anyway.
I found the hacked code in the description for the non-JP1 forum and removed it. I'm still trying to find out how they got in and what I can do to stop them.
(Jim also sent me a PM, but of course, I don't see those until I visit the forum!

)
EDIT: I've just gone through the rest of my emails (I stopped reading them when I got Nils' email) and I also need to thank Jim and Jeff for also sending me emails on the subject.
