Gregory's Server@Hyperlynx ED has a thing named "tele presence" where you can join another crew virtually to help out or ask for a mentor without the need to travel there yourself.
Most just go with a Wing though looking up a group beforehand and since the Odyssey DLC you can walk into a friendly ship too. These "guilds" usually run their own mentoring programs.
@bekopharm oh nice! I did find it very boring and sterile solo.
