Brief description from the site itself:
"Crowdtap is a new site that lets you ideate, engage and promote with leading brands, entertainment properties, non-profits and startups. Not only is it fun and easy to use but you earn cash for gift cards and charity for your participation. In fact, you earn your first dollar just for signing up."
I have been earning points for answering quick little questions, an opportunity to answer questions for free stuff and who knows what else will come up!
I signed up through Mrs. MFC, which gave her some credits, so if you sign up please sign up via this link :) I'd appreciate it.
Let me know what you think about it after perusing for awhile!
