I use a Google Site for my classroom webpage:
https://sites.google.com/site/carlsonhaldybiology/
I highly encourage people to use a Google Site as it is WAY easier to work with than something like Blackboard (in my experience) and a much more open approach. I don't like the idea of students having to sign in just to get to the course materials, and you can make a Google Site open to anyone.
I made a series of tutorial videos on how to do the most common things with a Google Site.
