I would like to thank you for this category and it is a great opportunity and idea.
However I have several suggestions.
1. These ads need to be vetted more carefully because many of them do not take you to the site that is advertised. This is either directly or with a redirect.
2. On the subject of vetting several states that no purchase is necessary yet when it comes down to it you have to complete a couple of offers among several to choose from and these are directed to pay area. So you have to pay in one form or another to get the credits (very deceiving)
3. I think to clear up the confusion the needs to be a "congratulation you have completed the requirements and have been awarded xxx amount of credits.
4. If no confirmation, then a confirming email so there is valid proof enable to get your credits.
I don't know about others, but it is very frustrating to put in the time (when you could be doing better things, like actually playing WGT) to complete this task and receive nothing for your effort.
Also you might consider allowing proxies on the individual internet service. I use a proxy (Open DNS) to use a family filter for my family and protect my network from viruses, Trojans, worms , phishing and much more.
Thank you for your consideration
