Ahh OK. In that case, it may be best to check out this Auto Friend module by AQB Soft that can be found here:

It seems like this will do what you need for making everyone on the site friends. It says you can "create" a list of members to be friends with each other so, maybe ask them if it is possible to do this automatically instead? Just a suggestion.
