Thanks! But it turns out that wasn't necessary... only reassuring.

Oh! That was the problem: I'd sent an invitation to david.tanzer@gmail.com! Now I've sent one to you... it says the invitation was sent by email, so you should look for it... but I see something on G+ that says you've been invited, and it shows your picture, so that's reassuring.

(Sorry for the confusion, but it's been so long that I'd done this, and it was so unproblematic before, that I didn't remember exactly how it worked.)

Let me know if there's any further trouble.
