I checked and your activation email was sent with no bounce or other issues on the server side. It looks like you are setting up a new user named @TW_Tones.
I have manually activated that account, so you should be able to login with whatever password you selected.
No luck with my prior account, no email received for password reset etc. I have signed up with google instead, could you possibly delete the existing Tones user name so I change my user name to Tones?
I have merged and deleted the Tones account with yours. You should be able to change your username.
Please add no-reply@talk.tiddlywiki.org to your address book, because the logs show the email was definitely sent. It will take a little time for us to get better non-spam ratings since this is a new email domain.
