Google groups and file sharing for skeptics?

I was wondering if there exists a Google group for UK skeptics? If not might there be any mileage in setting one up? Not for the chatter, which already takes place in a number of online venues but for the useful facility of being able to upload files (PDFs of useful papers perhaps) for storage / sharing among the group members.

There might be a copyright issue of course, in terms of storing other people's articles - but I could always write to authors and ask if they're happy for their material to be used and stored for this purpose.

In the next week or two I'll be collating a bunch of papers from the British Library (which will be bought for my own personal use so I expect I can't share them without falling foul). I'll be sending these to Trading Standards (TS) / Advertsing Standards Authority (ASA) regarding a local shop which is making some ridiculous claims in a leaflet (ASA) and on its website (TS). Having spoken to someone who worked in the shop it's clear that they consider that "people keep coming back / feel better" equals good evidence.

Anyway, if I were to get a bit more organised and email authors for permission for their copies to be stored in a small skeptic repository via Google groups... does that seem sensible?
