I updated a couple of things a while ago.
I think the concept should be that local cavers update the regions and caves they know about.
I have been principally been involved with the bradwell catchment, thus I've created and updated most of the entries on there for that catchment - along with others. I like the idea that the history of a cave can be written, and kept up to date, who dug what and when etc.
See the bagshawe entry - http://ukcaving.com/wiki/index.php?title=Bagshawe_Cavern
(good work JonP
Also - up to date access arrangements etc can easily be added/amended.
Surveys can be uploaded etc
With many hands making light work, I really do think it could be great - one stop shop for all info regarding UK caves.
