I will soon be submitting my Chat to the marketplace (https://forums.unrealengine.com/showthread.php?83566-Multiplayer-Chat-System-Loaded-with-features), and once it is published, what is the process for submitting updates to my buyers? I plan to update frequently, and am hoping that I don’t have to go through a long process of having it be checked out by the folks at Epic every time. What is in place right now for updates?
Thanks for the thread! We’re very interested in the update process too as we’re preparing our first submissions for the Marketplace. 
We’ll keep an eye on this as well.
Hey Jamendxman3, the support address is marketplace-support@unrealengine.com. The response time on there is pretty quick, and the team will have you set in no time. I’ve sent in a couple updates myself and the speed and efficiency is certainly worth noting. Best of luck to you both with your submissions! =)
i heard epic making some sort of publisher panel, to make this process easier
