Sorry about this, got no-where else I can post this to from work.
System16's domain name has expired, and the company it's hosted with (and who own the name), ZTnet, are not returning mails (all but 1 email address is bouncing) and the phone number listed on their who.is has been disconnected (I even called the states from the UK!)
I have managed to salvage the data from the site and backup the latest databases (properly I think?), so in theory nothing's been lost, it's still a collossal pain in the arse and something I hope to get sorted out shortly (before xmas with any luck)
I will almost certainly be moving the site somewhere else once this is sorted out.
Thanks for all the supportive emails I've been getting from those who have my private email address, and if you need to get hold of me please use my hotmail email email@example.com
Just an update and thanks for your time, if you see any posts about system16 being gone please feel free to copy/paste this response.
