Just a note. 2000 characters is not equal to 2000 words. I think max 1000 words is not long at all.
Currently it seems like I have to split if I type one or two short paragraphs (or about 8-9 full lines in total). If I go over the limit, it will discard my additions and I have to type again. It's really annoying.
I prefer using paragraphs to split long passage (not a hard limit or several posts). [Note: BTW If you split a long passages into several posts like what you do here in other forums, you would probably get a ban. :P]
Many forums have even ~10000+ characters etc. You can usually find a much longer post (10 times longer) than here.
