Identify available mailing lists, forums, helpdesks, in the planetary community

The planetary community is a rich and diverse environment.
A number of historical resources, mailing lists, helpdesks are available online.
@Trent_Hare recently posted some useful technical questions and answers from USGS astrodiscuss (thanks!! :pray:).
This thread would like to provide a list of those resources and their owners, in order to facilitate cross-posting and a more efficient and open information sharing.
