I haven't heard anything from Williams either! But after obsessively researching the "results" page, it looks like they admit later on too? I've been really nervous to ask too early because it's still kind of early March and I don't want to interfere with their decision by rushing the review of my application (if hastily asking even affects their decision). But you have an actual excuse to ask early, whereas I'm just being impatient - so I suggest to do it! Let me know how it goes, I'm dying to get more news!
