COMMUNICATION:If something unexpected comes up and for any reason you cannot meet the deadline or need to drop out of the swap, please let me know as soon as you know. If you take the time to communicate any difficulties, I can make sure things work out favorably for you and your partner with no hard feelings as a result. If, however, you just disappear off the face of the earth, you will not be permitted to participate in future swaps until you make good on your commitment.
