[Geocoding] Closing the geocoding mailinglist

[Sarah Hoffmann]

Hi all,

this mailinglist (geocoding at openstreetmap.org) hasn't see much traffic
in recent years. People have moved on to different modes of
communication, so it is time to close it down.

To follow what is happening in Nominatim and Photon, subscribe to the Github
repositories. This is also the right place for reporting issues with
the software.

Security announcements for Nominatim and Photon will be published in the
blog at https://nominatim.org/blog/.

For general question and discussion around geocoding of OpenStreetMap
data, the OSM community forum at https://community.openstreetmap.org/
is the best place. If your questions are more directly related to the
usage of Nominatim and Photon you can alternatively use the Github
discussion forums.

Thanks

Sarah
