Why not just... post it here (with the spoiler tag and a big RUMOR)?
This ^^^
Why not just post a topic for "Unconfirmed Spoilers" warning everyone before hand but giving the ones who don't mind being spoiled a chance to read it instead of having to pm you?
Seems like more of a hassle for both parties going about it your way since we would have to pm you and wait for you to get back to us if your not even on and you would have a bunch of pms to answer.
The topic idea is much better.
I myself don't mind being spoiled.
