Our online surveys

We have a separate team of people who handle our online surveys. When you become an OpinionWorld member, they will contact you when they are putting together a survey involving people with your member profile.

They contact you by e-mail with a survey invitation, so simply by going to your mailbox you can voluntarily participate in a survey that we have sent you.
