A number of free public lists are hosted on this site. You can manage your subscriptions to these lists from the following pages.
ProFox - the leading email support list for Visual FoxPro.
ProFoxTech - A subset of the ProFox list, with all Off-Topic messages filtered out.
Be sure to see the FAQ for the ProFox lists
ProLinux - a list designed to discuss issues for those who are migrating to Linux.
ProPython - a new list designed to provide help for beginner and intermediate Python developers.
Searchable archives of ProFox, ProLinux, ProPython, Dabo-Dev and Dabo-Users are available. I also host the archives for the Valentina mailing list, although I don't host the actual list. Info on that list is available at http://www.macserve.net/support/lists.php
I've added a spider-able link to the archives
