Hi,
as already sent to the tor-dev mailing list a week ago I planning to submit a well-known URI registration ( https://tools.ietf.org/html/rfc8615 ) so the verifyurl is at a static place and no longer needs to be specified explicitly.
Please let me know if you have any comments.

kind regards, nusenu
