Okay, here's a question for the community at large.
Once a thread is up and running, and a discussion is going that many Bears have contributed to, should the person who began the thread be able to kill it or lock it? Why? Hasn't the thread morphed into something that doesn't really 'belong' to any one person any more? How much ownership does the person who began a thread have after it has been up and running for a while? I'm not trying to discuss this in technical terms of legal rights, intellectual property or any of those kinds of things, but rather in practical terms of how this place is run.
Currently for a week or so after a comment is posted, the person who made the post can come in and edit it or delete it. That allows for second thoughts, but also insures that after a fairly short period of time the comments and discussion that the post was part of remains intelligible, and not riddled with baffling gaps.
