There is a high demand for players to be able to change the color of their glow, however the current method causes problems since not only does an admin have to do it, but it also changes the color of the player's name in tab. Since there is such a high demand for glowing colors I think it would be a good idea to add a plugin like Simple Glow, so OPs can change their colors without the complications that the current method has.
Thank you for your consideration.
