Any rules on "patch maps"?

Any rules on "patch maps"?

Just curious if there are. I currently have a set of them along with a list of changes text file sitting in a zip file, but one cannot submit zip files (probably for good reason). Would it be ok for me to submit multiple maps at once? Or would it be preferred for me to submit one map only?

just post them 1 by 1 but make sure they are worthy of being submitted and not just some crap maps or half-finished
