What is an annotation?

With each post on this site, you can leave an annotation, that is comments for yourself to read. These annotation are private, only you and the site administrator can see them.

You can mark articles with suggestions, mark up lessons with the progress you making. Even mark lessons completed so if you come back on a later date you can see that you've already worked on this lesson!

Also your annotations can be made public if you think they'd be helpful to others!
