To Matt Gough, the guy I've been trying to contact and send a Gmail invite to:

I've been trying to tell you that the Gmail invites that I've sent to you don't seem to get through (nor do my emails from my Gmail account, apparently). I'd sent you one before and one just today. Let me know if you don't see them (then I can just pass you the signup link).

Figured this was the best way to get your attention when I tried, in vain, to post a comment on your weblog (it says "registration is required" and I couldn't find a registration link - what is that? TypeKey?).
