Hello there,
we welcome you to the [tor-onions] mailing list, a place to discuss anything about operating and administrating hidden services. For example, it's a fine venue for questions about setting up hidden services at scale, or embedding them in applications and the mobile, or figuring out why your hidden service authentication does not work.
It is strictly a technical mailing list in the sense that discussing the content of hidden services is considered out of scope.
You can think of it as [tor-relays] but for hidden services instead of relays.
Finally, if you want to ask a question or make a comment about how to use tor, please consider using the [tor-talk] list instead. Alternatively, if you want to discuss tor development, please consider using the [tor-dev] list.
Enjoy!
