Rated 5 stars, it is truly excellent fan material from the guy behind the Travel! series (which is excellent). Strongly recommend if you want to offer your players a few additional classes that aren't overly potent and mix well with existing stuff.
Note for the creator:
I noticed a typo on The Fighter where "inspires" is spelled "sinspires". Additionally, "Will" is spelled like "WilL" in the document for Fighter as well. For Sage I did not notice any errors. Just wanted to give you a heads up since the document is otherwise very well put together.
Thanks again for offering this to folks, especially for free! :D
