Probably be easiest just to e-mail me at haremrpg@gmail.com with any corrections, although make sure to download the newest version to make sure that they haven't already been corrected. I do use a SVN for development where everything goes through docs and gets proofed before going into the game, but RPG Maker doesn't lend itself to that type of development easily so I'm very hesitant to give anyone access to the source code.
Send me a few of your suggested corrections through e-mail and we'll see what we can do to get those fixed.
