Im after a addon, was wondering if someone can point me the right direction.
What im after is a addon that changes the Guild members name colour, just like when you add someone to your friends list and thier name goes from Green to Turquoise?
Don't know any addon that does this... but there is an option in the Interface where you can change guild names to their corresponding class color, if that's what you're looking for?
Nameplate addons can modify the name colours etc, but only when they are within the minimum range that woud allow a nameplate to be displayed, 40 ish yards or something like that.
DocsNameplates offers various highlighting features which do exactly that, but due to that limitation will not make them more obvious from a distance.
