1) Material you post MUST be new to the comm. Best if it's brand-new, but since the point of the challenge is to provide your fellow members with lots of goodies to enjoy over the summer, no-go on re-posting material you've posted here before.
2) Be careful of spoilery material, now that on-set pictures, casting and plot information for S8 are becoming available. Using on-set photos for icons and other art is OK *if* it's not obviously spoilery. No guest stars; no OMG!!! type locations. Jensen and/or Jared standing somewhere -- including near the Impala -- in the type of clothes they've traditionally worn is fine. For instance: a brand-new picture of Jensen on-set frowning is not a spoiler. Really. It's not. Even if Dean got a new shirt.
3) No fair breaking up your icon batches to make multiple posts. Let's say: ONE icon post per day, per team member.
4) In deference to someone who feared this challenge would result in team members posting ... let's say "less than stellar material" just for the sake of earning points: make sure it's your best work. Make your team captain proud!
That's it! Now, onward to the finish line...
