From Dematis:

I would like GreenWall to be compadible with Incognito (https://www.curseforge.com/wow/addons/incognito) addon. Incognito allows you to set your main toon's name and inserts that name in chat before your message. Right now GreenWall does not transfer this insert across the guild chat, I believe it due to GreenWall working faster then Incognito. If you could make them compatible that would be great or add the feature that Incognito does into GreenWall.
