To post on the communtiy all you have to do is bring the community to the user info page. (The first page you see when you type the name in the search box). In that little box of options at the top...(it has a guy and a plus sign, A PENCIL, a scribbled upon paper, a heart etc. etc. Click on THE PENCIL. This is to post in the club. It will bring up a page identical to the page used for posting in your journal. Fill it out as necessary and click "Update Journal". It's as simple as that.
