The previous question, “getting help”, talked of the two major forums in which (La)TeX, Metafont and MetaPost are discussed; however, these aren’t the only ones available.
The TUG web site offers many mailing lists other than just
texhax
via its
mail list management page.
The French national TeX user group, Gutenberg, offers a Metafont (and, de facto, MetaPost) mailing list, metafont@ens.fr: subscribe to it by sending a message
subscribe metafont
to sympa@ens.fr
Note that there’s also a MetaPost-specific mailing list available via the TUG lists; in fact there’s little danger of becoming confused by subscribing to both.
Announcements of TeX-related installations on the CTAN
archives are sent to the mailing list ctan-ann
. Subscribe
to the list via its MailMan web-site
https://lists.dante.de/mailman/listinfo/ctan-ann; list archives
are available at the same address. The list archives may also be
browsed via http://www.mail-archive.com/ctan-ann@dante.de/, and
an RSS feed is also available:
