This utilizes a module for dice rolling - when you make a forum post now, you’ll see a Roll Dice dropdown, which includes a little help page.
It’s relatively simple to use, and is tamper resistant. You cannot see your results before posting, and utilizing “Preview” will keep your dice rolling entries. Dice are not rolled until the post is saved.
I have not actually played by post myself, so if there are other features commonly accepted in such circles, please suggest them. Their implementation depends on existing forum code that can be utilized or a coding wizard on this forum to implement.
Some pbp boards have a single fora for pbp gaming, which contains all of the games being played. Games played this way are typically divided into two threads: OOC (Out of Character) and IC (In Character). Examples of these forums would be rpg.net and giantitp.com.
Other boards create a subforum for each game, which contains a multitude of threads. In addition to the standard OOC and IC threads, there are threads for posting character sheets, campaign notes, XP awards, house rules, etc. Examples of these forums would be Unseen Servant and Dragonsfoot.
Incidentally, is it possible to subscribe to threads on the autarch forum, or sign up for email notifications when a new post is made?
Organizationally, what I could do is create a sub-forum for any given game (we’ve got a small community, so I don’t think this is outlandish to manage).
I expect that the Judge for the game will organize things however he or she sees fit, and (again, due to the excellence of our community) not a lot of policing or permissions enforcing should be needed.
Subscribing to either threads or entire forums seems possible, and I’ll put it on my list of things-to-do.
