I've got an idea on how I can prove my funds to you:

1. I PM you a screenshot of my mtgox account(s)
2. You PM me a specific amount of bitcoin (has to be less than .05) that I have to send to your bitcoin wallet within a minute.
3. I then post a screenshot of my revised mtgox.

Honestly man, this is all very dubious indeed, but I feel like we are both in positions to mutually benefit each other. I would not add any fee or anything and your bitcoins would be delivered within 3 hours.

There's still the element of trust that's worrisome, so I'd be willing to send the coins first to an intermediary member here that I know wouldn't scam me.
