Check this out. I think it is new. Google is now tacking feedbacks for Sponsored Links on the right side of Gmail. I have the screen shot here (picasaweb.google.com/hjr.photo ...) and if the link doesn't work goto my screen shot album (picasaweb.google.com/hjr.photo ...) and see the picture labeled "feedback for sponsored links in gmail...".

btw, can any one tell me whats the best way to link a picture here from Google Picasaweb.

sorry about the brackets in the links. Here are the fixed links to the screenshot and the album

screenshot :
picasaweb.google.com/hjr.photo ...

album :

Nice find.

Does it send the email too if you check send email test.

Yup. I guess it sends only the text...

Is it checked by default too ?

I mean the option to send the text of the email.

It's not new, I saw that yesterday too.
