Lack of solution or hints to exercises

[senpl]

There should be some way that when user could get solution or at least partial hint to provided forms. Without it when someone stucks it is clueless what to do.

Agreed, I'm trying to figure out the best way to do that. I have been working on videos, but that will take a long time to get through.

I used to have walk throughs for some, but they hard to follow.
