Hi there Frankarkohpaintsil, the "changeset comment" is intended to be an explanation of your mapping so that others can see what you have been doing. "Uccyouthmappers16" is not a good changeset comment because it doesn't say anything about your mapping. Better put something like "added buildings" or whatever it is you did! Also, you can combine several edits in one upload, you don't need to upload for every single house.
