These are Giveaway Events that have opened to the public and the idea is that you sign up for the events for Free!
Once inside you will be able to browse through all the gifts and download any or all of them in exchange for your name and your e-mail address for each gift, if you wish to contribute a gift yourself in order to build your own list click on the contribute link at the top of this page.
Many come with resell rights and sales material so it's a great way to build up your products arsenal and Information either for your Business or your personal use and study.
Bear in mind that for every gift you download that you are also agreeing to receive e-mails from the Marketer concerned in exchange for the gift so download only what you can use to save getting too many e-mails.
If you want to download gifts without receiving e-mails then you may want to consider upgrading your account via the One Time Offer upon sign-up to the Giveaways, this is usually very low cost and in most cases will give you direct access to all gifts on the event without signing up for them.
Remember that these Marketers have gone to a lot of time and trouble to provide you with these gifts so please respect that and If you are not prepared to accept e-mails from any Marketer in exchange for the gift then DON'T sign up for it.
