MrMikePatton,
We were actually just talking about ideas for something like this. We had brought it up to subscribers last year and nobody seemed interested at that moment. So we're glad you're interested.

I was thinking it would be better to handle this sort of thing at the tutorial level rather than the individual lesson level. Otherwise it would get pretty crowded.

Would you want a system where you "check out" (like a library book idea, where you register your intention to complete something before you begin) a tutorial and then mark it completed at the end, or would you just want to be able to mark it completed at the end?

Do you agree it makes more sense at the tutorial level, or do you think it would be better to mark individual lesson pages as completed?

Anybody else who is interested, please feel free to chime in.
