I know it`s been over a year since you created this, but you were the first guide when i searched for smartcasting, so i`m here to reply and help

First, just a common mistake, it`s teach instead of learn you, Second, you may post more videos of smartcast vs normal cast and maybe you could write a little more, give more examples, sometimes smartcast bugs, i think its good to mention and show examples and you could ask for people to read your guide on other guides comments.

See ya ^^
