[SSC] Membership form and payment set up

[Joss Winn]

Hello,

I've had a go at setting up the membership page and the method of payment.

As Jennifer found out, it's not as straightforward as we'd like. I've
had to provide a list of amounts to pay each month, rather than letting
people enter an amount. For some reason, PayPay won't let you decide how
much to pay on a monthly basis. The only way to do this is to donate a
one-off payment.

I've also created a form http://socialsciencecentre.org.uk/join/, which
is still very much open for discussion. I'd very much appreciate any
suggestions on what to include in the form.

I've tested the monthly subscription myself and it works. I haven't
tested the donate button, but I assume it works. The form works by
adding information into an online spreadsheet that can be viewed by
myself and David Young (and whoever wants to help with membership stuff!
- please do volunteer)

Anyway, I'd appreciate it if a few people could run through the form and
if you intend to join, use it and go through the payment process,
please. Feedback is encouraged.

Thanks
Joss
