<Snipped quote by Cyrania>

I can't speak for everyone, but I rather my crossovers be coordinated in advance. I wouldn't particularly welcome it if someone were to interject themselves in my plot without an invitation being extended first.

By which argument again, every post can more or less be in the present unless otherwise stated or previously coordinated.

Seconded. While I want interaction and actively seek it, there will be moments that are important for my characters to experience themselves without everyone else there.
