There are two ways that students can vote, one is through the blackboard community 2010 Undergraduate Voting after you log in - every undergraduate should be able to see this, as well as the banner on the blackboard page. The links are below as well.
To vote, follow the link matching the first letter of your last name alphabetically:
Last name starts with A - D
Last name starts with E - K
Last name starts with L - R
Last name starts with S - Z
The other method and way of gathering more information is through the Prove It! website, www.umbc.edu/proveit
where there are links to each finalist's video and a summary of their idea, and a link to the full proposal.
