Rails - Jun 2006 - finding duplicates in an array

an application i am working on sends emails to an array of users. it is 
possible for the user''s email to actually be in the array more than 
once.

i don''t have a real strong grasp of the ruby syntax yet, but is there
an
easy way to go through and either remove all of the duplicates or at 
least only send an email to that user once?

i just found something in the reference guide on the ruby site.

previously i was using something like:

emailArr << newEmail

but i saw this:

emailArr | [newEmail]

is this what i should do when creating the array? or is there a better 
way to accomplish what i need?
