But are the messages per moderately active poster going up or is it number of posters that are driving the message counts? If you have some idea of a cap on daily messages and we keep getting more posters then eventually we'll only be able to post once every day or so.
Is the number of postings a problem or the volume of post material? A huge, long, disjointed, post is worse than 5 short to-the-point posts. Could the volume limit be on number of characters rather than number of posts?
