Increasing the characters allowed for posts?

Hello! I was just wondering if you guys could help me out by showing me how to increase the number of characters allowed per post? A few of our features, especially The Crystals of Silveria have needed to be split among several posts because they exceeded the 60,000 character limit. I also am using standard heavily modified blog / forum messages as HTML pages since my only browser available to me can't do much with the actual HTML creator in the administration panel and some of those are dangerously close to exceeding the limit as well, plus I'd like to customize those pages further to make them feel like true HTML pages, but with such a strict limit, it's just not possible.

Is there any way that I could increase the limit to 120,000 characters? My forum version is PunBB and my website's url is: http://www.WiiWareWave.com

Thanks in advance.

Please note that it is not possible to modify any of these limits.

@SLGray for some reason my limit for posts is 5,000 less at 60,000 characters and my HTML character limit is only 50,000...is this a glitch?
