If you plan to write such a large post, perhaps it would be best to write it in a word processor and safe it as you go rather than trying to write the whole thing on the site all at once.
Pfft, come on, you'd be daft to think i'd write a 15000 word post in one sitting!
Most all my RP posts are written on MS Word, unless it's a quick comment in the OOC threads. I have at least 60 separate documents for my various RPs, RP related projects; even got some OLD old things that go back two or more years, right when i starting RPing for the first time... I SHOULD start using more of my time to work on the more "local" projects; that is to say, RPs outside of the forums, in person, but i always wind up doing this instead. I'll stop now before i REALLY get rambling on about the good ol days (about a year and a half ago)... so yeah. That's all i got to say, for now.
EDIT: No, really, the reference sheet i plan on posting is going to be
at least 15000 words. (Currently 40 pages, 9point font, widened margins... and it's still a pain to navigate.) I nearly got to (14XXX?) words, but i'm switching to a new, even more advanced format, which will make this one seriously big chunk of information. I think i'll do a separate post for each category, so that might be four consecutive posts. I'm hoping that it won't be a problem.
Thanks!
