I came across a new service called GroupNation http://www.groupnation.co.uk

Seems like a good concept. Basically you can create ad-hoc groups and then share photos, videos, have discussions etc. You can even log in with your Facebook credentials which makes it easier to handle.

Looks like I am the first customer on the site so I have set up a couple of groups and it will be interesting to see if it takes off. I suppose you could use Facebook Groups but not all my friends / family use facebook so this could have a bit more flexibility.
