The Australian Companion Rabbit Society has a lively email discussion group that is free to join, and is a great place to ask your bunny related questions.  The group is called CompanionRabbit, and you can learn more about it here.
If you have a houserabbit, and you want to join the Australian Companion Rabbit Society, to contribute to educating others about the joy of having a rabbit in your family, click here.  Joining the Society means you can choose to take a more active role in our group, you will have access to our members only website, and will be able to vote on issues that come before the group, and also propose your own ideas.  Members don't have to attend meetings, or have any responsibility - how involved you get is up to you !
