[rt-users] Guest users

[Wozz]

I was going to search the old archives, as I'm sure this question has been
answered, but the old search function is turned off, so I'll have to ask
here.  How does one go about setting up a guest user that doesn't need to
log in?  I'd like to do something similar to the way the RT 2.0 issues
stuff is set up on the rt web page now, except I still need the ability for
others to log in.  Whats the trick?
