I agree with every word @4Ruth says.
@aran, some of us with the best will in the world, are probably unable to make this monthly financial commitment. A suggestion…how about drawing up a system where instead of committing monthly, those of us of meagre financial means are able to make a one-off donation to SSi for any amount we can afford?
At least this way, we would be able to feel that we are making a small contribution to getting the show on the road.
I really feel there would be no need for you to offer anything in return for such donations - you already give us so much with this wonderful ssi system.
