Just wanted to get this out of the way, as there is a possibility that there may have been too many changes when creating the showcase, and people may be too confused with it's new structure to even want to participate in anymore. People may not even know what this thing even is now. If you feel you are in this camp and got any questions in regards to the showcase, please vote in the poll and share your questions here.
When creating the showcase, I tried to keep things as close as to EotM as possible as to avoid any form of confusion, but as with any change comes the possibility that change itself is confusing.
Don't forget to refer to this topic as it is designed to address most of the questions you may have about what's different and what remains the same between the Showcase and EotM.
