• CSS for the server status icon can be changed by replacing the URL in orange with the URL to your image. Then adjust the icon size in red to match your image.
• Add the server statuses to show into the serversToShow variable.
• Each server name in the list can be a partial name but capitalization is important.
• To match "[FR] Sirannon" you only need to have "Sirannon" in the serversToShow variable, or even just "Sir" since no other server name has those letters.
• If you add "ir" to the serversToShow variable, it will match "[DE] Gwaihir", "[FR] Sirannon", "Elendilmir" and "Firefoot".
• Make sure each server in the serversToShow variable is separated by commas, but the last server in the list cannot be followed by a comma (no comma after "Sirannon" in the example above) otherwise IE will break.
