[Mailman-Users] Getting users off old listserv

[heathcliff]

Hello,

We are all set to migrate our user community to Mailman, but we are at an 
impasse as to the most painless way to do this.  It is not enough to just 
inform them of the cut off date and send them a few lines of instructions or 
guides ahead of time.  Has anyone come across or devised a painless way to wean 
them off of the old listserv?  I have been checking around in the archives, but 
to no avail.
Any suggestions you can make would be greatly appreciated.

Thank you.
