I discovered a little known treasure today. FeedYes can make an RSS feed out of any website so you can use this for professors who insist you check their website on a regular basis.
FeedYes is a free service that requires registration. Setting up a feed is very easy, you just input the url address and a feed is created that you can add to any reader. Not all websites will work with this, there has to be so many links, but usually if a professor requires students to check his or her website often, there will a good enough amount of content. I was able to successfully create a feed for my mom’s website (who’s a marketing professor) so now I’ll get know when she updates her site.
