There are Super Good! but i dont feel like typing my guess in the forum.
A najs feature as you build up a libirary och Mini-lessons is there where a button next to The Fish for mini-lesson of the day insted of on the forum. kind of a bad way to watch the mini lessons especielly if you come in a year later as me. and you have to look thru all the pages.

If you had a mini lesson of the day then you could klick on in. get the questions think for awile then click another button to se the awnser. and one could even have a mail list to get the mini lesson of the day on one’s mail.

Tnx for a awsome site :)
