Change to LDraw.org Forums guidelines

[Orion Pobursky]

We've made a change to the Forum Guidelines to address the fact the PMs are now enabled. The follow paragraph has been added:

Private Messages

• Private messages are subject to the same rules stated above
  
• Private massages are monitored by the forum administrators and not "private" in the strictest sense of the word
  
• Private messaging is a privilege that will be revoked for a user permanently and without warning if any abuse of the rules is reported or discovered
