re: Doom & gloom?
To bring in new members you could add 'Like' on Facebook et al buttons.
And a quick tweak you could do. A book I mooched was lost in the post over Christmas. (I know it was lost because i was sent the empty packaging by the Royal Mail.) Both the sender and I have tried to mark this so I can get my points back, but the site says not enough time has elapsed and I have to wait until April.
