We all have questions from time to time.
Build your knowledge - Zero 88 training is free and well worth doing, there's the videos and, of course, there's the manual.
When you run across something you can't solve then you may be able to find a previous post on the forum for the same or a similar problem that will give you the answer. If not then the forum is the best place to ask, there's a lot of very experienced people in addition to the experts from Zero 88. You'll usually get help pretty quickly and it seems that someone from Zero 88 is keeping an eye on new posts at least during office hours and often beyond. Try not to have problems during the Edinburgh Festival though - they are pretty busy then 😁.
I've been lighting stages for about 50 years (DMX and desks as we know them now weren't invented for the first couple of those decades) but I still have questions and still learn better ways of doing stuff so don't be embarrassed to ask. The only dumb questions are the ones that aren't asked.
Enjoy your journey 🙂
