I hope this isn't covered in FAQ! I DID search for plug-ins and got a few hits but they didn't answer some basic questions. I need to try to promote my blog a little and heard about a thing-y that would make my blog show up higher on search engine, a certain "plug in." They call it the XML plug-in. But I don't know if I can use it, because I have a blog in .com. Do I understand correctly that I must be "in" wordpress.org to use it? Do I understand correctly that I must have a 'host' to be "in" wordpress.org? (I don't know what any of that means! Take "host." I actually have, pay for, space--a domain--on hostmonster, that I haven't developed yet. Is that what they mean by a host?)
Well, hope you can help and hope I can understand your answer! Please try to use little words and no abbreviations!
