Begin writing list of ideas

There was some brainstorming on IRC a couple of days ago where a few ideas were tossed around for things we could get people working on during a hackathon.
This begins the list of ideas and opens up to the forum to have more ideas added and discussed.
This like reads a little weird. I think you're missing a word "use" in "use quiz systems", and it's a little awkward to say 'courses such as in [subject area]'.

Maybe just say "A lot of first year courses use quiz systems like ...."?
