when I embed a project onto a site, it has these annoying white bars above and below the project. It's not that useful of a feature if it is one, and if possible, these should be removed for those that do not have a white background where you are embedding.

also, I noticed if the person viewing it doesnt have access to the alpha site, it won't show up. please fix!

With the release of the beta the access glitch has been fixed. The white margins on the sides of the projector frame cannot be removed, they are part of the embedding webpage. You can play with the width of the projector frame to decrease the size of the the bars on the sides, but the ones on the top cannot be removed.
