In over two years on the board trading heavily, I have had only one bad experience.
The person (which I will not name) agreed to a trade with me without having his end of the trade. Six weeks later, I had to ask him again for my end which he eventually sent. I will point out that it was not the agreed to trade - Opus X's but it was close. So, I did not bust him out.
Moral Of the Story - Don't agree to the trade without having your end in your hands (or Humidor).
Glad I got that Off My Chest! =)
Over All - Everyone Here Is Great!
