I have updated the mirror of asciilifeform's ffa to include the latest updates from loperos. Hopefully I will be able to resume more in-depth study of ffa in the coming weeks and can continue adding my own seals to the mix.

As handy reference, the following is the current Table of Contents for ffa as it stands currently, with corresponding links to loperos. I intend to mirror these articles here on site this spring as time permits.
