I finally got on to Google Wave and have 4 spare invites I can send out.
First 4 people to request them on this thread providing the email address they want it sent to get them.
I will edit the post and advise who they were sent to
Please note (from GW)
Invitations will not be sent immediately. We have a lot of stamps to lick.
OK first 4 pm's get it as you can't post your emails
Invites sent, sorry I did not have enough for all of you
