I don't agree but it wouldn't really work though, because if a user wants to delete a post then they could simply edit it and remove all content. The only thing it would stop is the whole thread beign able to be deleted by the thread starter. And I think the person who started a thread does have the right to delete it if they change their mind.
That and not being able to edit the title of a thread are the two things I prefer about this site over codeguru. .

Just my point of view. .
