Offers, Tasks and Surveys are targeted to you based on your location. It's quite possible that there are none available to you at this time because of this. The only suggestion we can give is to please keep checking the offers, tasks and surveys pages as we do get new ones regularly.
Please note that weekends tend to be slower for new Offers, Surveys and Tasks. Please do not write into the helpdesk asking why none are available to you. We're doing what we can to get more Offers, Tasks and Surveys for all members
