How can I tell if my trade offer was read?

I see my trade offer in my "Sent Items" mailbox, but I don't know if it was read. How can I tell?

Glenn:

It is my understanding that currently there is no way to tell.

Well, at least I got the "fame" of making the first posting on the new Strat message boards.

Just don't expect the groupies to be around forever.........shocking as this may seem.....the fame will fade......even for this.
