The Serious RP companion board is to be used for companion threads/OOC comments to RPs in the serious RP board.
A companion thread can be used for many OOC reasons.
Starting threads with rules, discussion of plot, character info, etc..
Participants of an RP may necro its companion thread when necessary. This means you may revive the thread even after four weeks past the latest post.
Potential participants may do likewise for the purposes of becoming a participant.
