yoji :
1. Pilot error - you never actually posted.
2. You broke terms of toms Hardware and so moderator deleted
3. You did post and you just cant find it
Most probably one of those 3. But could also be:
4. You posted in the wrong section and the moderator moved it to the right section.
In any case, if you go to your profile settings and go to "My Tracked Threads" it should be listed under there (questions created by yourself are automatically tracked). So if it was simply moved somewhere else you should see it. If it doesn't appear at all, it's probably because of reasons # 1 or # 2.
