I also fixed
kjhjkhjh . -> lkjlkjklj.
lkjkl , kkklj -> lkjkl, kkklj
there is no space because diacritics in english so
Pharo ? -> Pharo?
And I suggest to add some screen shots in the tour on pharo.
I converted also extra bold into == == because code should be in == ==
I think that we should have a special tag for the "exercises" right now
I put a bullet.
