If you are logged in to the forum, you can view the complete list of registered members by clicking on the Members button, typically found in the top menu bar of the forum. Once there, you'll notice that the list of members has 6 different columns: Name, Username, Group / Rank, Posts, Date Registered, and Last Online.
By default the member list will be ordered by members' display names, but you can re-order the list based on one of the other columns simply by clicking the column heading. Below is a list of each heading and how the member list will be ordered when clicked:
Name - Clicking this column heading will order the list by display name in alphabetical order. The list will reverse order by display name when clicked again.
Username - Clicking on the Username column heading will order the member list alphabetically based on the username of members. Clicking once more will reverse the order.
Group / Rank - When this heading is clicked, the member list will be ordered alphabetically based on the member rank and group names that the forum has. This will allow you to quickly see which members are part of a certain member group or rank on the forum. Clicking the heading once more will reverse the order .
Posts - Clicking the Posts heading will order the member list based on members' post counts. This allows you to see who has participated the most (or the least) on the forum very quickly. Clicking the heading once more will reverse the order based on the post counts.
Date Registered - When you click on this heading, the members list will be ordered based on the members' registration dates. You can use this to see who the very first members were on the forum, as well as who the most recent members are. Clicking the heading once more will reverse the members list based on registration date.
Last Online - If you click on the Last Online heading, you can order the member list based on the last time each member has logged into their account. This will allow you to see what members have been active on the forum most recently, or to view which members have not visited the forum in a while. Clicking on the heading once more will reverse the members list based on the last time they logged into their accounts.
