how to create a link to someone's zoo

In order to create a link to your zoo or a friend's zoo - you will need yours/their user ID.
To find yours - go into the help tab, on your zoo - and look here.

To find a friend's ID - go to their profile and it should be listed in the link of their main page - where these XXX's are : http://www.facebook.com/?ref=logo#!/profile.php?id=XXXXXXXXXX

If it's not listed on the main page - go to a photo page, or something linked to their profile and there will be a spot in that link that says ?id= the series of numbers after ?id= is the person's user ID.

Once you have yours/theirs - replace the XXXXXXX's in the following link - with the USER ID and you will have a link:
