FYI--- I have a pending deal with Ryan, but told him it was fine with me if he shopped the player around for a better deal. IMO he can't get one, if he does, great for him! In that case, I won't mind keeping my player.
My trade with MJK is a done deal agreed to by both of us.
My deal with Matt is silly and we both agreed to that. I sent him a confirmation email. Most of the time I do that so I won't forget what I did.
I guess as long as both parties know what is happening, it is not a problem. Just make sure you are on the same wave length.
