+* Matrix/Element
+Yet another encrypted chat/VoIP client-server, but unlike Signal and Telegram, [[matrix.org][Matrix]] is act ually open source. In other words, a project for nerds. We’ll be using Alphapapa’s latest [[https://github.c om/alphapapa/ement.el][ement]] project.

 * RPG DM
 Been working on my [[https://gitlab.com/howardabrams/emacs-rpgdm][RPG DM project]] for getting Emacs helping as a /Dungeon Master's Assistant/. The idea is to be able to roll dice and whatnot.
