New to me, looks an interesting resource.
The trouble with running web sites and forums etc (and maintaining the CF!) is that as a hobby it's fine while you are active and interested in whatever it is, but it becomes a chore and a consumer of time you would rather spend (or need to spend) on something else if your own interest/need declines. Then it is time to find somebody else to take over or for it to wither and die.
Before the Internet I would spend my "chill" time watching whatever was on the telly. Then I got active on a forum for cars, and there was a lot of non-car chat there too so it was a good social club. The Humax came along and I was looking for a user group, and at the same time the car forum was getting less active so most of my attention turned here. If something more important comes along I will have to reduce my activity - there are only so many hours available in the day.
The long and short of it is that it does not surprise me when amateur-run Internet things go moribund. The URL subscription is kept up for a time because the owner is reluctant to kill it and has forlorn hopes of a resurrection, but eventually becomes an unjustifiable expense and is let go.
If you have a keen interest in the content, and some time to spare, I suggest trying to contact the owner with an offer of help. You can probably get a contact address through a WhoIs enquiry.
