The current EVENT data is as follows
Lua Code:
EVENT_GROUP_MEMBER_JOINED (number eventCode, string characterName)
I think it would be helpful to add the displayName to the EVENT
Lua Code:
EVENT_GROUP_MEMBER_JOINED (number eventCode, string characterName, string displayName)
It would be useful information for groups with members that swap toons between raids, and saves authors the trouble of looping through the party to figure out who just showed up.
