One thing I do suggest before signing up is to get an alternative email address. I signed up with Gmail because you will get alot of spam. Also since you are giving out your phone number you may receive telemarketing calls. To solve this problem, you can sign up with http://www.simplevoicebox.com/registration_landing.asp, Aim Phone line, or you can hope to get an invite for Grandcentral. All of these services are free and will you give you your own number and voicemail. You can also just use a prepaid cell phone and use that as your number. I only do surveys that I am interested in and I also read the terms and conditions. Always read what you are joining.
