I've got a spare GMail invite. If anyone wants one (if anyone actually reads this site!), the person with the first comment and a valid email address will get it. I'm not going to be impressed if someone searches for a G M a i l i n v i t e, and comes up with this site, though, to claim it.
I know, I know, every man and his dog can get a GMail address now. Oh well.
(Mat, you don't count, as you already have one.
)
UPDATE: Please note that I don't have any more invites, so asking for them in the comments isn't likely to get you one. Sorry!
