Night Watch Player Notes (NWPN)
NW Player Notes is intended to be a guild and officer note coordination tool. Add a note to another player, guilded or not, and have it sync to all your guild and officers so that they know what shenanigans are happening. It also allows for private notes that only you can see.
Why NWPN?
Because it syncs with your guild! There are other great character tooltip addons out there, but none I've found that do guild synchronization.
NWRT?
Yes, if you have this addon it will integrate with the NW Raid Tracker and show you the notes of people currently in your raid.
