I inted to work through www.workwhenwant.com
i need full information about this site and the system they mentioned
like legitimate , honesty , history and any hidden information they
didn't mentioned and more .
please advice me

One warning sign here is that the site's text is identical to text on
several hundred other "work at home" sites.

I am involved in MLM so i consider myself qalified to comment on this.
I couldnt actally find out what product they sold from the website
which is always a bad sign.

I have been trying to find out what they do for over 30 mins which is not good.
I found this confused lady http://www.usask.ca/gsa/message/posts/3041.html
Also when i did the presentation,, the e-mail went into my spam box straight away.

Got it after over 1 hour.
Its using lots of different names to cover up what it really is

I am not involved in http://www.herbalife.com/ but i personally have
no problem with it.
Hope this has helped.
Now you know what the company is and what it does,, you can make a
more informed decision before you hand out any money.
