Very confused about how to use this!

I don’t have a clue how to use this thing. I didn’t even know what a New Thread was. Can someone make this very easy for me. I just want to read what others have to say about the best recipes, ask questions about new recipes, and put new recipes for others on the computer. Is there a really easy way to do this? I have trouble remembering things, and don’t hardly know how to use a computer.

Thank you so much!
