Google Wave had caused great excitement among people earlier this year. Now, that it has been released for the public, there are lots of bots, extensions and gadgets that help us to use Google Wave more productively.
Recently, Raju(Technically Personal) had written an article about how to edit Google Docs in Google Wave. I found that very useful and interesting, thanks Raju. He had used a gadget called as IFrame. I went a step ahead and tried to integrate in a similar way with that gadget, my Gmail account. But, it turned out that the page was getting redirected to my Gmail account itself.
Today, I found a great gadget that could help us integrate Gmail in Google Wave. Well, there is no specific name for the extension, it has just been called “Gmail”.
Follow these steps and add the bot to your Google Wave account.

This is how it would look after it is added! 
Enjoy Waving!
