The first thing you show is a signup page. Why would I sign up if I find no value in the site?

"Where the world comes to learn"

If it's a forum, learn from stackoverflow, reddit, 4chan, etc: give everyone your content, and if people find value and want to contribute, they'll sign up.

Yeah, I was pretty fuzzy on what exactly the software is/does.

A video would be awesome. I would understand them wanting to provide some layer of security for students/teachers by not allowing open access, but a demo area or even some screenshots would solve the "What am I signing up for?" problem.

true, thanks for the feedback! I agree it is hard to understand the product simply from looking at the first page, we have an about page at http://www.homeroom.me/about and screenshots at https://angel.co/homeroom, but we'll definitely create some sort of video or demo where we can show teachers how exactly the website is used.
