Invite codes: administrative/record-keeping

[redbird]

I sent out two invite codes on Saturday that haven't been used. If you're one of the people I sent one to, and you didn't need it, please let me know what code I sent you, if you remember. It didn't occur to me to keep notes at the time: if it had, I probably would also have thought of looking around and seen who had said they no longer needed codes.

Conversely, if I sent you a code Saturday and you do want it but haven't used it yet, again, please let me know. The one I sent Friday is identified, and there's no rush on using it.
