Posting in the "Chat rooms and Message Logs" section.

This section will be a log of all private messages shared between users... naturally, only the characters involved would know.... Basically private communication logs.

In the case of messages, do "User to User".. All messages from that point on forever between those two specific users would go there. These exchanges can only be person to person

In the case of chat rooms. label them as "Chat Room Name" "(Users involved)"
