I'm entering my fourth year of teaching, and I've had some sort of website up pretty much since I started. I've used iWeb, Google Sites, Hype, and most recently, Weebly. About once or twice a year, I get the website-redesign itch. It usually comes with a sort of revamp of my classes themselves.
This summer has been particularly big on the revamping. I'm trying to automate as much as I can so I can have less stress and more time to work on my masters degree.
Anyway, check it out at mrcollett.net. For right now, only the main class pages work, and the disclosure information is still in progress. (So much for destressing my school year. I spent too much time developing the logos for my classes and units.)
