Finally got around to updating this Skript resource for anyone who wants to use it.

List of changes:

• The Thorns enchantment no longer repels tagging.
• Optimized the scoreboard so it fits better while on screen.
• Removed decimals from the coordinates of the tagged player.
• Removed unnecessary statistics from the tag scoreboard. (There is only stats for how many times you've been tagged now)
• There might be more but that should be it.

Fixed a typo in the syntax causing the current player who is "It" to not show on the scoreboard while they are offline.
