As someone new to the IETF, how should I go about doing the following? I want to find some information about IMAP and its extensions. Let's say I found RFC 1730. How would I know that it had been obsoleted by RFC 2060 and then by RFC 3501? How do I find the extensions? I don't necessarily want to search through a list of 5000 entries to find what I want. That's where I think a naming scheme like IETF-IMAP would be handy. Then I could look at a list of IETF-IMAP and see IETF-IMAP-2003 would be newer than IETF-IMAP-1996. But that's beside the point. As of right now, how do I find this information? Is there a handy tool on tools.ietf.org that I should use? Thanks for your help.
