Why You wants to delete your thread?
Are this takes space of your Hard Drive?
Are this forum told you not to exceed certain amount of threads?
If we all do this kind of things, nobody will able to find any solutions out of any search engine.
Instead, this will be better to post the Solution you found by yourself. That will also helps you to get more right and best way if someone knows and post better solution than your's.
So removing content or event deleting threads is a crime to me.
You must visit this thread over this forum. This will change your mind for SURE.
