This my first posting on a forum. I’ll attempt to cheer you up in your frustration, so, herewith a quote of Max Beerbohm’s : You cannot make a man by standing a sheep on its hind legs. But by standing a flock of sheep in that position you can make a crowd of men. 
Welcome. I’m sure you’ll get the hang of it soon.
If anything is unclear, you can simply ask, helpful people will engage you. It can be daunting, that first step.
