Hey guys! I just created two new forums, "Official DLC Discussion" and "Rock Band 4 Discussion". I moved a bunch of threads to the second one, so if your RB4 thread is missing, don't panic! "Official DLC Discussion" will have an admin-created topic for each DLC release, and you'll be able to use those threads to rate them from 1-10 and otherwise discuss the content.
See you in the new forums on October 6!
