 We definitely need to pay some attention to Hypermail's performance, which leaves much to be desired, and I suspect there would be other advantages to using a database.
 Does anyone have a good argument against adopting dbm/gdbm? I've made very little use of them, and don't know much about the drawbacks, like whether it would create significant installation problems.

 I will also look at your monthly rotation script before too long.

 I don't know. A separate list for user support might not attract enough expert interest that the questions would get answered.
