It is courteous to acknowledge messages which are received.
If you promise to send information, exchange badges, etc., keep your word.
Do not use language which could offend others.
Be aware of cultural and language differences. It is better to be too polite than to use slang or language which might imply another meaning to your brother or sister Scout on the other side of the world.
Be cautious about giving your address or telephone number on the internet. Never do this during a “public” forum. Ensure that the young people check with an adult before giving out personal information.
