PHP open source chat add ons

I have found a open source chat code that can be altered at <[login to view URL]> but there is a few extra admin functions i want adding to the admin console x7 chat added to admin console 1)option to add user ranks at end of name in bracket example: Admin (Admin),,,so if i place a tick in show rank there will be a space between the nickname and there rank 2)Certain rank has different coloured nickname Example: Admin (Admin) 4 colours Black,Red,Blue,Green....all nicknames will start out black unless changed 3)Certain Ranks have @ at the front of there name Example: @Admin...if a tick is placed in show @ in the rank then that will show @ at the front of all in that rank 4)Max Room User can only be set by certain ranks otherwise only 10 are allowed in the room 5)Certain ranks can mute a member without it showing in the room......if this is ticked the ranks can "supress" a persons text so it does not show in the room like mute but will not say "this person is muted" You can either add them to the code or make a mod to add these to the chat code
