Hi,

I agree with Rejean.
Learning baseten is quite hard for the beginners due to the lack of  
substantial examples.

I believe it takes huge amount of time to post tutorials like CarLot.
Anyway, it would be nice to have simple relationship examples to  
download just to excercise with.

Hillegass's Department - Emploee example would be fantastic.
