[Projects] project sponsorship

[Tom Kralidis]

Dear OSGeo projects: we are preparing sponsorship materials [1]
in the next few days to send out in the next weeks.  As part of this
exercise, we will articulate which projects are accepting sponsorship,
usually via a link to their website/etc. with instructions to potential
sponsors on how to contribute funding to a given project.

Example of sponsorship links below:

- GeoServer: https://github.com/geoserver/geoserver/wiki/Sponsor
- QGIS: https://qgis.org/en/site/getinvolved/governance/sponsorship/sponsorship.html
- pygeoapi: https://github.com/geopython/pygeoapi/wiki/Sponsorship

We welcome projects to submit their sponsorship URLs for inclusion
to our sponsorship call / communications for 2021.  This will provide a
valuable opportunity for communications and marketing of your respective
project funding intake.

If your project has a link/page/URL on how to accept sponsorship,
please feel free to send via this email thread, in the ticket at [1], or email
me directly.

The due date for submission is Friday 05 February 2021 at 18h UTC.

Thanks

..Tom
