The member list is in order by # of posts, so right now you are probably 40-50 pages into the list. That position constantlt fluctuates. i have better luck finding prople who put a location on the profile, so I do not have to read every name. You can use the "My profile" link above to edit or change anything public in your profile.
From the home page, each section has great instructions on how to navigate and use the site. They really do help!
Welcome!
