Hello, this is my first week with Rails.
I'm working to create an app that has Users associated to instances by
their email address. For example, like Yammer, those with the email
domain "yahoo.com" only see what others with the same domain see...
Also like Basecamp where you only see your stuff but it all lives in
Is there an authentication plug-in that supports that? ie
1. Registration that is email based (no usernames)
2. Users are assigned to an instance based on their email domain, and
only see data that is associated to their instance.
Lastly, as I'm new should I start with Rails 3 or stick with Rails
2.3? From what I can tell
Pro of Rails 3: I can learn fresh from the start
Con of Rails 3: Plugins are all for Rails 2+
Thanks for any thoughts or pointers on the above.
