I do not care for it. Some posts call for a simple answer. No need to flower up the reply to make it 15 in length. i.e. If I post a thread entiltled "pics of my new truck" a simple "Nice!" will suffice. I see what you guys are trying to accomplish with the rule, but the problem could be better handled with proper moderation. Besides it is never a good idea to implement a rule that is so easy to get around. BTW, there is no such thing as a "pointless reply". Everyone is entitled to their own opinion and in their own words. Maybe try disabling posts counts. That will cut down on short replies and post racing. As for SPAM I do not think the 15 limit will have any effect on that at all.
