Take a quick gander at a useful application that could be used well in conjunction with this site its called www.Twitter.com.
A good example is for quick access to mobile devices such as mobiles etc.

So why not create a group called after your home town or one for your favourite club and keep people informed.

For example I have created a temp one called Woking.
