Additional notes for MineSync installation. Most of the installation process is documented in the other articles and in notes next to each option both within the MineSync config.yml and in the XenForo options (and the MineSync tab). Some features are not documented there and instead information on those is listed here.
In S_2.1.2 we changed how link colors are to be defined in this config.
For server versions OLDER than S2.1.2: the value of KeyCommandLinkColor should be a Minecraft color code (single character ONLY, for example 'e'). Full list of color codes here.
For server versions from and including S_2.1.2: You cannot use Minecraft color codes for the value of KeyCommandLinkColor. You must use one of the following: black, dark_blue, dark_green, dark_aqua, dark_red, dark_purple, gold, gray, dark_gray, blue, green, aqua, red, light_purple, yellow, white. They must be written exactly as in this list - if there are any mistakes in spelling there will be an error when messages are sent.
IMPORTANT: UPGRADING TO S_2.1.2: You should edit your language.conf manually and set KeyCommandLinkColor to one of the above color codes. MineSync will fall back to the default of yellow if the syntax of this value is not valid.
