I don't trust MtGox/TradeHill/any other site that requires you to "deposit" funds into before making a transaction
Interesting that the seal would just disappear though, I remember seeing it yesterday
It goes away when you log in to keep clutter down.
Let me know if it's not there when you logout.
Additionally you shouldn't trust someone just because they have a seal.
I'm not sure how an exchange is going to operate though that doesn't receive the funds before you make a trade.
Open to suggestions. I'd prefer to not hold any funds at all if that is a possibility.
