Hi everybody,

Based on feedback from our users we decided to make an island with
some simpler missions. This island will be opened with Home Island right
after registration so a user can start solving missions on either of them.

I know that many of you have some teaching experience so if you have
any ideas or propositions; please do share!

Bellow you can find our first set of task for this island.
