I believe the character limit on DW specifically is around 300,000 words, give or take, so that may be less of a concern depending on how long your average word is. Still, TL;DR might be a plausible concern if it's going to be a great deal longer than 10k words. XD

"Master Link" posts may end up being the way to post, depending on exactly how overambitious some writers get to be. XD
