Common sense, standard decency, politeness & family-friendly please.
Keep in mind, this is a discussion forum, not a place for rants and what would be more suited to your blog.
For any pedants, the following are specifically non-acceptable:
- Nudity (feel free to type your content nude, just don't upload nude pics)
- Sexual comments about other members
- Violent comments in relation to other members
- Any negative comments regarding another members family, their upbringing, their intelligence, their sexuality etc
I would also like to add, that if a topic is not directly related to 2012 (such as the U.S. Presidential election candidates) and it's controversial (homosexuality, bigotry) it's much better suited for a blog, and not a friendly discussion forum.
