There are mods to put a specific usergroup as rainbow color in the forums, however they don't appear rainbow colored in the shoutbox, they just appear dark grey. Is there a way of making this possible?
Questions/Problems regarding modifications/styles need to be asked in the modification/style thread. That is where the support for modification/style is - not out here in the main forums. Please note that if a modification/style is unsupported (or even if it says it is supported), you may be on your own if you chose to install it.
