There is no BEST place to get info, but there are a lot of places that have info. Some of them are friendlier than other, some have a lot of bias one way or the other. Don't believe everything you read. Don't be afraid to just try things, this is a DIY hobby. Find folks who live reasonably close to where you live and go visit them, ask lots of questions. Go to every event that you can reasonably get to like Christmas Expo or many of the one day local events that take place all over the country. Connect up to the zoom room and just listen as you do other things. I do not think FB is a good source since it is conversational and not an indexed repository of data, but there is a lot of quick answers and lots of different opinions. Be careful of joining to many FB groups as you can get overwhelmed and again lots of bias by a lot of folks. I have been doing animated lighting for 15 years and have seen a lot of changes in hardware and software. Start slow and realize that is a year round hobby and is not an inexpensive hobby. My golfer friends spend more money on golf than I do on lights, lol. Do it for yourself and share what you do as opposed to doing for someone else, your motivation is better this way. Have fun at all times, but it will be aggravating and frustrating as you learn. Even after 15 years I still make mistakes. Did that just yesterday trying to repair some stuff and still don't know what is wrong, sigh. I put it away for a couple of days and then will come back to it.
GOOD LUCK
