feature request: allow schleuder to send a welcome message to new subscribers with the list public key attached
This idea came up in testing a use case where the list public key wouldn't necessarily be uploaded to the key server. While sending email to firstname.lastname@example.org works fine, for less technical users it would be useful to preempt the need for this step and just have them receive a copy of the public key along with a brief message about the list and maybe even how to interact with the list via email commands. Maybe even an option to include a blurb about the web interface, since not all deployments may have that available. I'm thinking something along the lines of how mailman mailing lists send welcome messages to new subscribers, but also tailored to make getting started with schleuder easier for the masses who may be less technically inclined.
