Your jam is included in our jam browse pages. Very long jams may not always be in the calendar if they are far off or are taking up a lot of space, it depends on what else is going on in the calendar. You should always promote your own jam though, don’t expect itch.io to provide you with all your participants. We get dozens of new jams created per week and we can only show so much. As a host you’re responsible for making something interesting and getting the word out. If you’re able to get people from your own network participating, then itch.io is more likely to want to show your jam to more people. Hope that makes sense, thanks
