Puerto Rico.com is open to everyone in the http://www.
Even if you are not a member you can read the post, as a guest.
However, your personal information is guarded.
That is why your email and real name is not posted, unless you do it yourself on a post, which I strongly don't recommend.
Free speech works both ways. You can said whatever you want under those guidance, and everyone in the WWW had the right to hear you.
