Packaging Module for Marketplace.
Design and Skin Customization
This is in place now - you should see a "marketplace" option in your profile menu - that will allow you to create a private release channel.
You will also see the option to add your Developer Prefix in your profile settings - make sure that is set to a 2 digit prefix (i.e. "kr") and that you have the SAME value set in your developer tools module on your development system. Once that is done and verified, you'll see new options in the Developer Tools -> Tools menu for packaging modules and skins.
Once you have packaged a module or skin, download it to your system. Then come back to Jamroom.net here and CREATE (or update) the marketplace item. You will be able to add it a PRIVATE CHANNEL only - that is it's not going to show up by default in a user's marketplace on their JR system. You will however be able to post the invite code so users that do want to get your item can add the channel code to their marketplace and then get updates from your channel.
Let me know if that helps.
