Only post with your own username, even if you know the username/password of someone else.
Keep your own password confidential.
Choose descriptive titles for your new topic (not titles like ‘Helpppp!!!’)
Choose the proper category for your new topic
Try and keep your responses fairly short. If you have a lot to say, think about starting a diary or start your own topic.
Take care with your spelling
Used normal mixed case (not CAPS which are considered to be SHOUTING)
Address other users with respect
Keep your language clean
Flag offensive posts to the moderator rather than responding to them
Flag to the moderator any posts that you believe are from a minor
Quoting relevant portions of previous posts may be helpful, but do avoid habitually quoting large chunks
