I saw you made an edit to the Entrance page and manually reverted it. Let me first welcome you to the wiki. I see you must have read my guidelines post on the wiki, as you seem to have attempted to make a tabview page. I'm going to suggest you start with something slightly easier, these things can be confusing. Also the entrance really doesn't need it's own page in SSE, it's just the Hall of Heroes. We haven't renamed old pages to prevent links breaking, but will (probably) get to it eventually.
If you're interested in editing, there are a great many things that need to be done. Check out the guidelines post on the forums, or contact me or one of the other admins.
