I checked your site and the Q2A section is indexed just fine (try searching site:yoursite.com/qa/ in Google). It's probably just that it's fairly new and doesn't have many links to it, so it's not coming up on Google searches. You just have to be patient.
Welcome to the Q&A site for Question2Answer.
If you have a question about Q2A, please ask here, in English.
To report a bug, please create a new issue on Github or ask a question here with the bug tag.
If you just want to try Q2A, please use the demo site.
