Thanks Jeff I appreciate you being willing to do this work at all so I am reluctant to gripe. When I looked at MPI 2.2 I did not notice that the opaque directories are each a month, not a day. My mistake. I guess there is a trade off. If a list goes on for thousands of messages it is good to be able to filter by month. It does seem that finding the start of a thread can be hidden by this month by month structure. For example in Feb (http://lists.mpi-forum.org/mpi-22/2008/02/index.php) there is a one item thread with title "Re: [mpi-22] FW: [mpi-21] Proposal: MPI_OFFSET built-in type ". Most of this thread was in the prior month but that is not visible if you come across it in Feb. If you find the thread in the prior month (Jan), the forward links are there and the Feb comment will be found but if you first find it in the 02 folder you do not see that there is prior discussion. My real concern is about being able to find and follow a complete thread across its lifetime even if that lifetime is long or has big time gaps. It looks like following forward is there but finding the beginning or knowing you are not at the beginning can be more difficult. Is there a way to provide back links into prior months when using the thread view? Once we are doing MPI 3 and have threads that date back a year or more it could be more of a problem finding the whole thing.

Is this view helpful ("thread" view for mpi-21 and mpi-22 lists):

http://lists.mpi-forum.org/mpi-21/2008/04/index.php http://lists.mpi-forum.org/mpi-22/2008/04/index.php

It's the "thread" view. It does separate by month, though.
