When scheduling persistent world events on the Neverwinter Connections calendar, to help them stand out and attract the desired types of players, it's recommended to:
-- Use the prefix "PW:" in the title and make sure your PW name and connection info is listed in the game description
-- Describe the event, including whether it is a one-time occurrence or a regularly scheduled DM'd campaign on the PW
-- Indicate the general types of players/characters the event is for (RP, Action, high-level, low-level, etc.)
You can see the NWC Quickstart Guide for additional information on game types and creating them in the calendar.
