Wikidot provides two main ways of keeping up to date with what's going on with the site with out having to visit.
- Watching Pages
- RSS Feeds
Watching pages is the easiest. All you have to do is click on "Start watching this page" at the bottom right hand corner of the page, and you will be sent an e-mail whenever the page is updated. This is a good option if you are interested in one or two subjects and you want to know when there is a change, but if you start watching everything on the site your inbox could start to clog up very quickly with notification messages so it may not be for everyone.
It is all a bit tricky to take in, but I think it is worth the effort of at least looking at the Google Reader link above. It wasn't immediately obvious to me when I first signed up how Google Reader would benefit me, but I use it a lot now.
If you do decide to use it, here are a few LGAM feeds that you might like to subscribe to.
