https://github.com/wiremock is our official organization on GitHub. We host all the key repositories there, and we use .github for organization-wide settings and configuration templates.
Owner: WireMock Inc. Most of the engineering team members are admins there. For community support, access, etc. please use the community Slack.
There are plenty of GitHub repositories related to WireMock which are hosted outside our official GitHub organization. Normally we have no access to those repositories, and cannot help with administration there. Normally we recommend transferring such repositories to the official GitHub org.
In some cases forking might happen if the repo is stale and the maintainer is not reachable.
