Now I still have 3 Google Wave invitation left. So if there is still somebody need Google Wave invitation, just leave a comment with your email address. I will send it to your ASAP.
The previous version of Opera Mobile I tried is 8.65 but I was not impressed by it. When I found there is Opera Mobile 10 beta available to download for free, I decided to give it another try.
Finally, I received a Google Invitation from a friend today. It seems that my theory about the invitation mechanism of Google Wave is not correct. Anyhow I am happy to have the change to try it while there are still a lot of people requesting their invitation.
What I am interested in here is the way how invitation of Google Wave works. It is not like how invitation of previous Google Products works.
