Some common mistakes writers make imo include it's/its, her's/their's/our's/your's (none of these ever use an apostrophe) who's/whose, their/there/they're, who/whom, and effect/affect. this is all strictly grammatical but it seems many people could use the refresher.
thanks for clarifying! i like your gen idea.
