I am also interested. I tried looking for the url of justask and my browser just shows yahoo search. Can you post the url of justask. I also think that the offer is tempting. I tried looking for kasamba too. I just have to find time to sign up.

I had joined one of these sites a long time ago. There was a long process before they enrolled you - but in the whole year I got only 3 questions to answer and 2 of them were in fields totally disconnected to my field of expertise !!
These are useful sites only if people go there to ask questions. You have to pay to have a question answered in some of them.

Whaaat?! You have to pay to answer their clients' questions? Isn't it supposed to be the opposite? What do we get for answering their questions then? I thought these sites are created so that people would have their questions answered by PAID experts.
