Hee hee, another Pratchett fan!
If you buy books Nick, there's a link on the top toolbar to 'DSF Shop' - this links through a site called 'Spend and Raise' which is for non-profit orgs and charities to raise funds and there are many retailers one can access via this route. The customer doesn't pay any more, but the retailer gives a small percentage of the price of the goods back to S & R, who then pass it back to the charity/organisation.
Thus we pay for our webhosting and things like when we've had a summer meet on the lines of a picnic in a park, we also have been able to hire a meeting room for the same afternoon, in case it rains. Well it was showery to begin with 2 years ago so we just dived under the gazebos but it blew over (the rain not the gazebo) so the room didn't get used. But we do know what would happen if we didn't have the room to fall back on!
Formerly Admin were paying for it out of their own pockets and we kept saying, that's so not fair, now we all know it's established and useful !
This way anyone can support it and there's no embarrassment trying to offer donations, with one being able to and someone else not - and best of all - it costs nobody anything!
