Needless to say, the green highly outnumbers the purple or gold.
I use four scripts, three for adding and one for deleting from highlight strings with a .cmd script, so it takes all of 2 seconds to label someone.
In my opinion, it's helpful to know if a person is OOC or not, as my character would see those who are OOC as insane, and therefore not interact with them. Right now, I have 620 people labeled, with around 85% of them being OOC, 13% in-character, and 2% roleplayers.
Just wanted to share this with everyone ;o reg

. Usually one blatantly OOC remark is enough to get you on the OOC list, and the roleplayer's list means that you are ACTIVELY roleplaying, such as being a participant in the Vishmiir shard quest.
