I revamped the social network sharing links on the site.
A Facebook "Like" button is on the right side of the page header. When someone logged onto Facebook clicks the "Like" button, a story appears in the user's friends' News Feed with a link back to http://www.cyburbia.org - not an individual page.
Below that are icons for Twitter, Facebook, Reddit, LinkedIn, and a drop down menu with more options. Clicking on these will take the appropriate action (Tweet, Facebook recommend, etc) with the individual page.
Your Cyburbia username or details about your Cyburbia Forums account are not revealed when you or anyone else click on any sharing links.
Have fun with the sharing links!
