That’s not a tacky question at all, Lauren. I’m glad you asked. We encourage you to “recycle” our resources, but we don’t have a good and secure way to facilitate that on this forum. To get in contact with a potential buyer or seller, you would need their personal e-mail information or other contact information that you don’t want posted on the Internet for all spammers to grab. Unfortunately, we had to turn off the private messaging feature here because of a bug in the software. I hope that’s temporary, but in the meantime I’m not sure how you could share that private info securely.
You might check into the yahoo group CMCurricula. It’s set up for buying and selling used CM materials.
