Hi Kacir,
I take it from your response that the "Are you 18?" problem is persisting? It's quite possible you found a bug. We will try to replicate. Don't worry, I don't take any this as criticism. If there are any bugs remaining, I want to find them and stamp 'em out.
For the profile, click on "Profile" then click on edit account information (
https://www.smashwords.com/account/edit) and you can toggle the over/under 18 field (but not yet the email address). Again, though, that would help only if you mis-entered, but you didn't because no kids joined the last couple days.
Any chance you have the contact information for Mr. Galloway? I'm not finding it on his site.
Thanks again,
Mark
