Pages you can jump to in this web site are identified by a single word with two capital letters.
FirstLast seems to be a standard way to do this with real names, however any word with two capitals will do. Once you have created a page with a suitable identifer it will be underlined if the page exists, otherwise a question mark will follow. To create the page simply click on the question mark. That's that. For instance, here is the MemberList.
