I agree with those who are verifying their inventory is correct before sending a proposal. I have traded on line since 1994 and have always verified I have the cards, but don't pull them until trade is accepted. I quit pulling because I don't like to restock cards. Recently, I have found by verifying cards for a trade that my TCDB inventory was not correct, it's happened several times. I've also had cards that I received in a trade that have not gone into my TCDB inventory, they were still sitting "in transit". The trades were all processed properly, so they should have moved to my inventory, but didn't. That's just another reason why I verify before sending a proposal. I understand the automated system works properly most of the time, but for me, each individual is responsible to verify their cards on either side of the proposal.
