You can read back copies of "General Aviation" online here.
My reaction when mine dropped through the letterbox this morning was the same as Rustle's. It will appear on the above website in due course (the paid-up members deserve some privileges!)
Have a read through some of the back numbers and see if you think the work being done is worthy of your support (less than an hour's flying cost per annum).

While on the subject of support, how about those with no personal title getting round to spend a few quid on supporting this website which allows us to voice these online opinions?
I think it's very presumptious indeed to lobby for contributions to another organisation through a medium for which you haven't contributed yourself!!
