I've just approved 4 pending GMCMH-EFI membership requests. I did not
approve a 5th one because there was no indication in its request of any
GMCMH association -- a mandatory requirement. I apologize for the delay in
approving requests. For a long time, I got an email notification every
time someone applied for membership and could immediately, in one or two
steps, approve/disapprove the request. Then Google stopped sending those
notifications. Now, they've made it even worse: Instead of merely acting
on the request, I must copy the name and address, change to another web
page, enter that information (in another, never described, format, type a
greeting message (can't keep one), and execute several other steps. TOO
MUCH TROUBLE, GOOGLE! :-)
Welcome aboard, all 4 of you (I HOPE).
