Used stamps exchanges.

I am new to this club and have been allotted 2 exchanges. While one exchange was successful, the other exchange partner has backed out, expressing inability as the member has his/her hands full.

So the question is how do I cancel the registration so that the slot would be freed to take up another trade?

Thank you!

Exchanges can't be canceled. You get the address of a random member. You have to send the stamps to this member. After your stamps arrive at the destination and are registered, another random member will send you stamps.
