Also planning ahead (which can be done by just mentioning "hey I'm going to do this in my next post, that okay?") helps prevent the kind of contrived scenario you mentioned from happening. I also prefer back and forth rather than huge collabs because honestly, it means people are less likely to just merely skim over it and thus won't miss out details. That and all of the collabs I've taken part in over many, many years of doing this (like, since the late 90s) have... Been a huge mess, really. ^^;

...I do still kind of like the idea of Chikori vs Guls, honestly, and... Well, spoilers, but I plan for her to get knocked out in her second fight and probably attribute her initial victory to being a fluke. So, um, yeah.
