The only contact information I have for you is your email address, so it is important that this is correct on your profile. Do please check it is correct by choosing YOUR ACCOUNT>EDIT YOUR PROFILE.
If it is wrong, and you have a Username that ISN’T your email address, then you can change the email on this Profile page.
It’s slightly more complicated if you use your email address as your Username. If this is the case, contact me and I can sort it out.
