With a tip o' the hat to Lady Shadow I feel like the odd one out here. I don't see the problem with resurrecting old threads. This is a site for mental health support. Each of us is at a different place in our personal journey. I might have heard something a million times, learned what is being said a long time ago, but it might be brand new information to someone else.
A suggestion for those who dislike old threads being being reactivated - skip over the thread.
