The single repo https://github.com/schemeorg/community now has the
contents (and git histories) of these 4 earlier repos:

- events.scheme.org

- lists.scheme.org

- research.scheme.org

- standards.scheme.org

I'll delete the separate repos (which were under
https://github.com/schemeorg as well).

The following subdomains would benefit from being handled as
self-contained entities, each with its own infrastructure, so let's
continue to keep them in separate repos:

- files.scheme.org

- registry.scheme.org

- try.scheme.org

The following are still under the https://github.com/schemedoc
organization, and it's probably a decent place for them:

- api.scheme.org

- doc.scheme.org
