@brittandjosie Thank you. I am overwhelmed by the support. I learned a lot this week. I was introduced to the Terminal by @wes.philbin who was exceptionally welcoming. I got a lot of invaluable guidance from @shadowspub, who has been very helpful to me from the beginning. Also, the links that @slobberchops kindly placed in the comments here about Demystifying the Hive were extremely helpful. Then I did a bunch of my own research.
I still have much to learn, but it was a good start I think. I feel much less anxious and lost.
(Many other people were very helpful also, of course. It's been kind of amazing.)
