We don’t offer phone support, but you can get help from the Discourse team by sending an email to the support address that is given on your site’s admin dashboard.
You can also get lots of support through this forum. If you ask your questions about metrics here, people will be able to respond in writing. There may well be members of our public forum who would be willing to have a 1 on 1 call with you, but if you don’t get a response, please contact our support team, or write out your questions here.
