Very warm welcome here @Moira.
You just introduced yourself in a way so you don’t need to go anywhere else.
About techy things on this forum, in the thread Really useful ‘How to’ stuff and other great posts you can find various “how to” stuff and other interesting and useful things. It’s all in that list and clicking on the links they’ll bring you directly to the desired thing behind the link.
Well done on coming here and introduce yourself. If you have questions, you can always ask them or in separate topic created by yourself or in one of equivalent to your question topics and you’ll surely get quick answers to them. Since we’re from allover the world there’s always someone reading the forum almost like in 24/7 businesses.

Hwyl!
