A heads up to a recent change in the contest rules. Your random awards now have expiration date. They will expired 30 days from the day you receive them. I have set the expiration to the awards you have accumulated before the change to 60 days so you have plenty of time to use them.
To check your current awards, go to the contests page and click on 'My Activity' tab. Here is a direct link: http://www.buxr.com/awards
