But I'm not talking about re-writing history. Several times I started a thread, but then I didn't feel comfortable, so I tried to delete them before anyone posts on them, and I couldn't. I could edit them, so all you would find in the thread is "Couldn't delete". I think deleting it is better than this empty thread.

About re-writing history, I agree it's not fair for others, but still it can be done with the current option in editing. You have 4 hours to edit, which allows many responses to follow.

Unless there is no count on the number of threads that you can delete using the report button, I think the delete option is a reasonable one as long as there are no replies.

Eventually, I can leave them the way they are, and no harm is done. But deleting them would be a nicer option.
