locked threads are just pushed down the list of threads as new ones appear...over time they get pushed back down the line untill you have to go to other pages of the forums in order to see them. Theres no point in removing them as people still might want to read locked threads.
as for the hosted site thing, its been talked about a lot...believe me, i know some of the sites are pretty much dead at the moment but they do have content on them..(apart from bones of life) so people can again still read them and get info from them.
Bones of life was a big site when it was in its prime so its not like we can just can it because it isnt doing much at the moment. We'll just have to see how things develop. Now that there are a few more people on the forums, maybe this will motivate some of the old webmasters to build up their sites again.
