I've got three invites left, pm me if you need one.
I had 4 up until I sent
latch one.
UPDATE : crfpilot, sargorn and LNCPapa, check the email addresses you provided, invites on their way.
That's all I had left for now, but the last batch I got was 15 in three days. I ran out of people to give them to, so if I get more I'll post back.
