That's great, thanks for chiming in!

If I could make a suggestion for KeyCombiner, I think that having a way to start out as an anonymous user (with no sign up or email confirmation) at first, and then asking users to sign up once they've completed a few lessons would make it even more appealing to try out.

The "Start Learning" button at the top right of your site IMHO should be a bit of a demo mode.

(I know that it's harder/messier to implement a "half anonymous" mode -- this is just a suggestion) :-)

I see your point and I wouldn't mind having something like that. However, much of KeyCombiner requires a database. It stores practice results, personal collections, you can change a lesson's combinations etc.

I feel like if I tried to do a demo mode without storage anonymous users would be left with a 2nd class experience and potentially think less of KeyCombiner.

However, there's already lots of things that anonymous users can do: Browse all public collections, courses, and lessons. Use the practice demo on the home page. Search through KeyCombiner's entire database of public shortcuts. And more.

Why not let “semi” anonymous users — i.e. they’d be identified by a session cookie, but you wouldn’t know their email - use your database and store a bit of info there, but limit what they can do at the application level i.e. don’t let them complete more than 3 lessons for instance?
