Like many popular developers, I keep a .plan file: Cataboligne.org
For anyone in the dev community who wonders where this .plan file thingy came from: Catb.org
I use mine for keeping mod development on track, and it goes back a __long__ way!
I was just posting some updates in the Archon forum: Moddb.com
And I happened upon .plan notes for 97 - 98. Back then it was just log.txt.
Thats pretty amazing, I was under the impression that all notes prior to '03 were lost.
Now I gotta look around some more. (Back to squishing bad loop bugs in a bit..)
