If you can't find this confirmation email in your inbox, it's either because you made a mistake when you typed your email address during registration, or because our confirmation email was mistakenly directed to your spam or junk email folder.
So please check these first, and if still you can't find our confirmation email, just try to register again and double check that your email address is typed correctly.
Before doing so, you might want to add firstname.lastname@example.org to your contacts to make sure our email isn't mistaken for spam/junk.
