I can not be the only one that goes directly to a campaign's details page to check to see when the next game is at a glance, it's a useful feature for a busy player! But you can not fight lazy. Some GMs are overworked and updating when the next game manually for each session is just always going to be is too much hassle for some members of our most precious portion of the roll20 user base. It is my understanding that a GM is given the option to broadcast the frequency of the game, daily, twice weekly (Biweekly), weekly, every other week (Biweekly), Monthly, etc. when putting the campaign up on the looking for group service. My proposal, a new Button! It takes the aforementioned frequency information and adds it to the previous "Next game will be" time to adjust the next game time displayed on the campaign's detail page.
