I don't know whether that's a regular feature, or if it's just for the coolest kids, but I just noticed the birthday cake icon next to Cubs' name on a post. Didn't happen to notice it on the board heading, but it absolutely caught my eye next to the posting! I like it.
I do stuff like this from time to time in order to generate threads for the Site Feedback forum, which I don't seriously address. (I'm testing against Yahoo!'s cache by changing the window title on the index page, mostly)
