Interesting...
Not sure of how viable charging for email is?
I know as I am trialing it at the moment. Take a look here:
http://www.chislehurst.co.uk
Chislehurst is a very expensive and exclusive place to live, and therefore thought it might take off!
Even printed 15k leaflets to deliver. Had a friend hand deliver 2,000. Not a single response.... hmmm. Don;t think I will continue down that route!
Maybe there are some glaring issues with the site, as I am suprised there was such a lack of interest. Oh well, nothing ventured, nothing gained!
