I think this is a great compromise. I live in the United States, and the conversion of Pounds to Dollars would bring my annual membership to $49.80. I can afford it I believe, and have actually not bothered yet to send it on because I had an issue with some of the mandatory questions asked online when you join.

Thought about ordering the back issues to help out instead and there are several I am interested in and will do that soon...
Would be more than happy to contribute a separate amount to the unkeep of the forum, been having a lot of fun here recently answering PM's, posting, and such.
