The guidelines reminder does not appear for every submission

It appears the first time you submit, once more a day later, then three days later, then a week later, then once per month.

People have mentioned now knowing the rules thanks to this dialog so it does seem to be working to try to improve the titles being submitted

Edit: If you think it's too much effort to click a few checkmarks once a month, then yea, please don't submit. We do want people putting some level of effort when thinking of new titles
