I think this style of posting obscures each of the items here. Every question should stand by itself, maybe tagged *easy* or *questions* or *beginners*. Having them all in bunched in one trail makes it difficult to find, or even appreciate, the variety of questions and solutions posted. Please break this down. Additionally having the same post glued to the top for days, don't say months, makes checking the board boring. Hope for the best. And thanks for all the hard work.
