Create Speciality Collection

1. No collections for entire leagues (e.g., “The NFL”), or for current MLB, NBA, NFL, and NHL teams (e.g. “The Chicago Cubs”) since these exist separately. You are, however, welcome and encouraged to create collections for particular years, positions, etc. (e.g., “The 2016 Cubs”; “NFL Quarterbacks”; “Buffalo Bills Kickers”; etc.). Be creative!

2. Before creating a collection, check to see if the same collection already exists. If it does, talk to the admin about adding additional items. But please don’t create duplicate collections.

3. Be aware that from time to time we likely will delete, in our sole discretion, specialty collections that are not being maintained and / or not generating enough interests on the site. So please try to create fun and interesting collections that others may want to enjoy. Then keep them fresh and updated.

4. All posts must comply with out Terms of Service and Community Guidelines.

5. Have fun and be kind and supportive of each other!
