A Question About My Threads?

[Stark]

Now, I've had my account since April 19 2007, and when I go to see all the threads I've started, the oldest one is October 22 2008, now, I am 100% certain that I have posted at least one thread before that, it was entitled "Is This Normal?" in Puberty 101 I can't remember exactly what it was about, something about my sexuality, I was worried I might be gay or something, but I remember the name because I've got other threads under the same name about a similar topic. I don't know if there are any other threads of mine missing. So what happened to this thread, and possibly others? Did it get deleted? If so, why did it get deleted, there are dozens of other threads talking about people worrying they might be gay, so there's obviously nothing wrong with asking that, even if it was too similar to other threads, shouldn't it have just been locked?

Some threads may have been lost if it was during a crash of the database, and the back up was before you made the thread.

Whatever the reason, you cant expect them to stay forever.

Is This Normal? (http://www.virtualteen.org/forums/showthread.php?t=31732)
Is that it?

Other than that, it may have been lost, or deleted for some reason.
And like Andy said, don't expect all threads to stay here forever. All servers have some unreliability.
