Using the Mentions Box:
This box is only
for use in tagging members to let them know that their character has been mentioned in a thread, owl, or news article. For example, if your character says "Harry Potter did it!" in a thread, you may link to that thread in the mentions box so that Harry Potter's player knows they were mentioned.
This box is not
for chatting or letting another player know that you have started a thread for them. Those found using the Mentions Box improperly may find their privileges revoked.
