Here is an update for vB 2.2.8

In admin/index.php find:

makenavoption("Add","user.php?action=add","|");
makenavoption("Find","user.php?action=modify","|");

Add this right below it:

makenavoption("Mass Delete","user.php?action=massdelete","|");

This code doesn't exsit in admin/index.php of version 2.2.8

| Now open /admin/index.php, find ...
| 
| <a href="user.php?s=<?php echo $session[sessionhash]; ?>&action=add"> Add </a> |
| <a href="user.php?s=<?php echo $session[sessionhash]; ?>&action=modify"> Find </a><br>
| 
| Replace that with ...
| 
| <a href="user.php?s=<?php echo $session[sessionhash]; ?>&action=add"> Add </a> |
| <a href="user.php?s=<?php echo $session[sessionhash]; ?>&action=modify"> Find </a> |
| <a href="user.php?s=<?php echo $session[sessionhash]; ?>&action=massdelete"> Mass Delete </a><br>

Which is why you have to use the code at the top.
