Hi Chris,

It's always worthwhile to read about sites that have disappeared, especially if they can be related to existing sites, and to see their original position in the landscape as a whole.
For example, the site below seems to be just a crop mark, but is nevertheless interesting.
http://www.themodernantiquarian.com/site/4319
As there will probably be nowt to see on the ground, the question has to be whether the purpose of TMA is as a website to direct enthusiasts to ancient sites that are visible on the ground, or to direct them to all sites, visible or not., which are of prehistoric interest.
Personally I'd like to see all sites listed, as long as they can be filtered out by those who don't wish them to clutter the website up, as has previously been suggested.

Cheers,
TE.
