Please stop adding your own commentary in the margins. It's incredibly rude to both the readers and (if you care) the author.
It's like someone in a movie theater in the row behind you constantly offering their insightful comments while you're trying to concentrate on the movie.
If you really must tell the whole world what you think about the work, add it to a page at the end like all the scanlators who value the audience, their own efforts, and the authors.
P.S. To be clear I'm not denouncing the bits of explanation, it's the personal opinions.
