I was under the impression that when you paid for Gold Member ship it was a lifetime subscription?

Although i'd gladly pay for the privalage again.

Perhaps worth charging to advertise your car and/or parts will help raise funds to keep the site going.
Although for example only a £1 charge per post in parts for sale i'm sure most regulars will be more than happy with that for the service, and a online payment scheme will make it very easy.
