Very simple mod that allows moderators to change the tag (and optionally colour) of other players, and adds a little functionality for players to write actions they undertake (RP-oriented mainly).

List of commands:
/Tag :[Admin only] Change another player's Tag and optionally colour. (/Tag Player;Tag;{r,g,b,a}) .
/ResetTag :[Admin only] reset another player's Tag and colour.(/ResetTag Player).
/me :writes message as action. (/me Action)
