We have had many people using Yahoo mail report that they are not getting their account verification emails delivered to them timely. From what we know so far there are two ways to work around this so far: 1) Add the email address "firstname.lastname@example.org" to your contacts and attempt to verify your account again. 2) Use a non Yahoo mail email address. Going forward we are working to fix this problem, but for now the two options above are the only things we have that will work for Yahoo mail users, other than waiting for the confirmation email to eventually arrive. If you have any other ideas for workarounds do tell! Thanks!
