Hey, Steve, I humbly suggest that you plop that Escape Pod favicon.ico file into the root of this new subdomain, and that you also put in a robots.txt exclusion file.
Hide these forums from the search engines (just the forums, not your sites themselves) and you won't have spammers showing up here trying to ruin it.
Remember, Steve, forum spamming is not something people do for a hobby... it's a cottage industry at this point, and there are programmers who actively sell forum-spamming software.
It's only a matter of time before updates to those noxious programs include the functionality to spam a Simple Machines forum.
Right now is the perfect moment to hide the forums and insure that they remain spam-free for good long time.
