"Hello World" discussion and queries--

Hi there. 👋 I’m curious about my “Hello World” discussion; it hasn’t appeared yet. Also, since I created two posts, I’m a bit confused by how pages are numbered with 1, 2, 3, etc… On second thought… the second post didn’t include [Mary5]. I believed I had entered my full name, but apparently not. My apologies for that. I’m not particularly tech-savvy, so thank you all for your assistance.
