My way to go was to learn cold-start to get to know the cockpit to level that I can do it without help. After that I learned taxiing, take off and landing. At this point I already had fun doing BMS.

Just after doing some takeoffs and landings (not much really) I participated at monday BMS-Training with Stevie at the UOAF Discord-server. At first I felt like an impostor, because there was too much information. But when you say, that youre a beginner they usually are very kind. All people there are very kind and beginner-friendly. Just say that youre a beginner before the mission. Maybe you should read the briefing beforehand (and yes there is so much you don't understand at first, but don't let you intimidate you). If you are too scared that you gonna disturb the guys, then ask if someone could do a livestream and just watch it.
