I'd think other people would also hate that. I would. :) Anyway, if it's
intentional then be sure to set subscriptions=yes for that namespace too
(although I think it's default anyway).

mbox and maildir are completely different mailbox formats. In mbox a
single file contains all messages, while in maildir each message is in a
different file.

So Ahsley-Dec09 is a file? It sounds like you're using mbox, so you
should use:

location = mbox:~/Mail-Archives

(the :LAYOUT=fs is unnecessary, because it's the default with mboxes

It's probably a good use of namespaces, although it would be simpler if
you just put archives under ~/mail/Archives/.
