This is my first grid - on reflection it would have been better to use lower case for many of the clues. Particularly given the font. Is it community etiquette to re-publish a grid?

The wall “rules” as set by the site are that each clue should begin with a capital letter. It sometimes causes problems but I think it’s a good rule as it keeps entries consistent. I think you’re correct about the font though: Al and AI look identical despite being made differently. Not sure there is an etiquette except, “No matter how good the grid is, it shall never leave Page 1 scoring 5 stars.”

Good idea but plenty of crossovers possible meaning no unique solution.
