My generic reply
Welcome! Hope you decide to join in.
The exchanges are great fun...and VERY addicting.
Anyway. You send your info....name, address, etc to the person hosting the exchange.
When the sign-ups close, that person will do a random draw and PM you a name and address that you are to send the item to.
You post on the thread that will be started after PMs are passed out, when you mail off AND when you recieve. Do not say who you are sending to....that is a surprise until they post about their goodie and tell who sent to them.
Shop and mail off by the posted date.
Sit back and relax

and wait for a goodie package to arrive to you.
Hope that helps.
Any other questions, just ask away
and more specifically:
These are the last of the alphabet exchanges.....we started last summer with A.
You send things that start with the letter "W"....one thing or more than one......in the $5.00 total range.
Hope you join in ......loads of fun!!
