Can Unofficial Groups use the Pledged feature?

Pledged is specifically for packs with a green light, so to avoid confusion with which packs are official and which aren't, we aren't planning to make it useable for unofficial groups, but thank you for asking!

Unofficial groups are pretty much IC only, but the suggestion of using custom titles to denote ranks is great! You could also set up a makeshift hierarchy list in a Pawprints topic!
