Wait....
The OP is not able to PM yet (not enough posts)
I think that is why she/he wants members to post their email address so as to where to send the details.
However, IMHO, I think maybe if it was done privately, and the OP could make a few quality posts (15 and over)
and then be able to PM back.....
OR
send him/her your email address in the PM whereby he/she could send details to you by email.
Is that correct? OP
Has this giveaway been approved by the way?
Hope this clears this up?
