I can't post in general?

This is my first time back in almost 6 months. Tech is no longer the focus of my life. I'm looking at building a new tower for the first time in 10 years. Tech has changed a lot. I wanted to start a thread asking for feedback and suggestions. But I can't post in general. I keep getting a message saying I'm not allowed.

But I can post here.

What's the deal?
