Please be kind and respect one another. Treat others as you would like to be treated. Politeness goes a long way.
Respect privacy. Please be respectful to users who do not want to share private information.
Have fun! Conversations can be fun. Don't take yourself too seriously (it is casual after all).
Spread the word! With more members, the more chances to converse with people you don't know. It's also up to you to help grow the tribe.
