Paul,
I am the web master for the MPBA and am sorry to hear you can't get the membership form off the web site. I have just tried and it works perfectly! What programme are you using to open it? I use Foxit and that is OK. I don't have Adobe Reader, but will install that and check it out. I suspect the problem is not with the PDF, but with reader programme.
I will try to send a copy by PM, or if you PM me your address I'll put a hard copy in the post.
Regards,
Barrie
MPBA Webmaster
