Thanks, Sabrina, that was one of my questions.
I asked this in the prize thread but I can see I should have put it here...
I will not be able to participate after the first week or so of Oct. It is fun to just participate - but I am curious - is it necessary to do all the challenges all month in order to be eligible for the prizes? I can send in a few cards early for that part of the challenge, but I will not be around again until early Nov.
