user emails only link to clearnet address
User emails (for account confirmation or forgotten passwords) which contain verification links, only have the clearnet version - ie they link to a URL which starts in 0xacab.org and ends in something like /users/confirmation?confirmation_token=blahblahblah
Would be nice if there was also an onion version of the link in the email, to save having to copy and paste the end of the URL.
