Right... so, I've sent another case specific inquiry to London and hope it won't cause any issues that I've sent two, asking pretty much the same thing, within about a week. It turns out I did in fact misspell my email address the first time so even if they chose to respond, they wouldn't have been able to. Does anyone think this will cause any problems? They say not to send the same email twice, but I did explain in the second one that I had miswrote my email address the first time around. I just asked for a status update and to make sure that I hadn't missed any communication from them, like requests for documents.
It's a fairly simple reason for the mistake. I use a Hotmail address for everything, but they wouldn't accept it as valid for some reason. So I had to use my yahoo address, which I hadn't even logged into for several months. When I logged in, I wrote it as "yahoo.ca" and it worked, so I assumed that was my address. But if you actually send email with .ca at the end, it comes back as a mail delivery failure notice. It's actually "yahoo.com." If Yahoo hadn't allowed me to log in when I was misspelling my email address, I would have realized it was wrong. Such an annoying and stupid little mistake on my part.
