How can they take out your thread if you haven't posted it yet?
Usually, they will delete duplicate threads. Are you posting articles, or personal screeds?
I *think* either an entire tread of messages can be deleted or just an individual post. If the thread is off-topic or offensive, they can take it all out. If it's just the one post, then they can just knock out the one post.
In either case, they are apparently supposed to give a reason. They have not been doing so. The thread has simply been deleted when I tried to go back to it.
Neither of those first two ideas appeared to apply in this case, and it happened to me about three times tonight.
But, like I said, maybe I missed something.
