Since this is an online convention we have some special requests of our GMs to include when posting games.  
  1. What RPG system are you using?
  2. Do players need to be on video? 
  3. Will you be using a virutal tabletop or other software in addition to Discord? 
  4. Do you plan to record or stream?
  5. Are alternates guareteed to be seated?

In the title for your game please note at LEAST the main tool/tabletop you plan to use besides discord.
For Example: "Skies of Glass:Spare Parts [Roll20]"  

Finally think about how you will provide information and character sheets with your players. Whether by virtual tabletop, PDFs in Discord, Google Drive link in your game description, or some other means
