Is there a way to see all post from (memberX)?

On other forms I belong to, if you click member x it let's you see/follow their post.

When I try that here it keeps saying I'm not allowed blah blah blah.
Is this not possible here?
Am I missing something?

Thanks in advance 

The option to see someone's posts is found on their profile, but you can't view profiles until you have 15 posts.  You need 12 more posts to get there.

So how do I go from guest status to a member?

Same deal, it's post related and all spelled out clearly in the site rules. Hugs, Tracey
