1, The deletion does NOT mean your words or opinions are right or wrong;
2, The deletion is topic-oriented. The whole thread, or branch of a certain topic may be deleted. Again, this does NOT mean your words are wrong.
3, Try to think over before you click the "submit" button when you post. Try to respect others and don't attempt to fight back to "bad" messages. Those "bad" messages will be deleted sooner or later.
4, This forum is a place for discussion, not for fighting. I hope every word can be kept forever and everyone is proud of what he/she has written in this forum. So, before your posting, think about it, "Will my such words be kept forever?"
5, Hope everybody enjoys this forum. Thank you for your co-op.
