I am also new but I think you just need to add to Users model: has_and_belongs_to_many :users.

check out self referential associations - it is exactly what you are
looking for.
the problem with doing has_and_belongs_to_many :users, is that you will
still need a join table that ''holds'' these associated records.
give it time, it looks daunting at first, but it works. :)
a couple links:
i worked with this
* http://blog.hasmanythrough.com/2006/4/21/self-referential-through
although it is clearly outdated, and there are probably better things
out there.
i also googled for a sec, and found
*
http://lists.rubyonrails.org/pipermail/rails/2006-February/021193.html
* http://blog.dnite.org/2007/6/8/howto-has_many_friends
(same plugin)
* http://blog.dnite.org/2007/3/14/has_many_friends-released
anyway .. check out google for self_referential; that''s the way to go.
hope this helps!
shai
