Honestly I think forums are a thing of the past with all the more current platforms we have now to communicate. For instance I know where everyone is I talk to here on Twitter, and often discuss the performances from The Voice in those group chats.
The only reason I stuck around here was for the Idol Games section, but with all its memories and data inaccessible, I wouldn't want to start all over. So I probably wouldn't rejoin a new IDF, but I'll definitely cherish the memories here. It's been a ride.
