UPDATE: I talked to someone on WordPress’s instant chat.
Although NONE of it STILL makes ANY SENSE,
Here’s what he told me.
1. That there is a difference between wordpress.com, and www.remarpro.com.
2. THEN he told me, the “plugin” option would only become available AFTER I got my domain (which I purchased FROM WordPress) HOSTED BY SOMEBODY ELSE.
Fine, I say. WHATEVER you say.
So I purchase a webhost, dreamhost, I believe it’s called.
And now, I’m just waiting for some more support regarding the matter.
Any insight appreciated.
