1) I was the one who put a google wave link in the wiki, I tought it might
be a good way of comunication because anyone with a Gmail account can acess
to a wave and use it. If someone do not have a Gmail account he/she simply
can use the IRC, can contact anyone that's helping via their wiki's and also
can use this mailing list. I do not see any problem there.
You might not see a problem but there are people here who have an irrational
fear of Google, yet use stuff that could be considered more evil.
