@Skeezyks, thank you so much for your thoughtful reply.
Part of it is learning, for example, I tried to find my post by looking in "new posts."
It isn't listed. Then I found out I could trace my post and found it here. Then I realized I should look in the actual space I posted it.
That seems logical, but I don't think I remembered where posted it.

I don't know what my goal is for PC. I think just being able to post and feel connected.
I appreciate your response. It really helped me understand.
