Hi Scaredguy,
I don't know if the mods can delete entire threads but.....
If you just leave it alone and don't worry about it, it just fades away to the back by itself.
I started a thread once and it went on and on and people were getting all mixed up in other stuff! It drove me nuts! But then it just disappeared off the radar.
Maybe, just ask them to "lock" the thread, that would get it to disappear faster.
If you go to the list of people online now, there will be highlighted names or different font for moderators. You can private message one of them if you like and discuss this problem.
I know the thread you are talking about, and it is nothing to worry about. Perfectly valid and no harm done.
