I don't know if there is a (database imposed) limit on post size, but since we are playing RPG games rather than writing Fan Fiction, I think there is an unofficial, practical limit to the amount of text that should be in a post. Since each post is presumably one characters telling their part of a tale, chapter length expositions would seem inappropriate. With that in mind, hopefully we won't see people finding out if there is a size limit, at least not in RPG (and NEVER in Mirth!
).
