WSN Gallery can display a listing of online users, if you've enabled it in your switches. Online users lists in WSN Gallery act as toplists, and so can be used in the same way as any toplist.

You can configure the online user lists under settings->functionality. The next value it requests, the number of minutes to count the user as online, will determine how lenient the definition of "current" is in showing currently online users. Anyone who loaded a page less than this number of minutes ago will be listed as online. Finally, set the date format you will want to have shown in the user listing as the last seen date of the users.

Suppose you want to put a new online users list somewhere, or modify the ones in the default templates. Click 'toplist generator' in your admin panel to start his process. Choose 'online users' there, and specify the rest of the toplist as you wish. Alternatively, here's an example you may wish to use:

<table>
<!-- BEGIN TOPLIST 5 -->
<CONFIG>online,time,50,descending</CONFIG>
<tr> 
<td> 
<a href="http://scripts.webmastersite.net/wsngallery/manual/memberlist.php?action=profile&id={ONLINEMEMBERID}">{ONLINENAME}</a></td>
<td> 
Online from {ONLINESTARTDATE} to %x - %X
</td> 
<td> 
{ONLINEBROWSER} {ONLINEIP}</td> 
<td> 
{ONLINELOCATION} 
</td> 
</tr> 
<!-- END TOPLIST 5 -->
</table>
