The Settings > Options >Who's Online Option
allows you to control the display of http://www.example.com/forums/online.php
- Who's Online Enabled
This is the master switch for the Who's Online page. If you select no, anyone who tries to access the page will be shown a no permission page.
If you select yes, you may still control usergroup permissions for Who's Online via Usergroups > Usergroup Manager.
- Who's Online Refresh Period
If you set this to a value greater than 0, after that many seconds of being on the same page in Who's Online, your browser will automatically refresh the page.
- Who's Online Display Guests
Controls whether guests are shown on Who's Online. Browsing registered users are always shown.
- Who's Online Resolve IP Addresses
If you have permission to view IP addresses on Who's Online, this controls whether you will be shown a raw IP address or something that has been resolved to a name-based host. The name-based host cannot always be resolved, but when it can additional information about the browsing user can be more easily determined (for example, his or her Internet Service Provider).
Resolving IP addresses to names is a very slow process. If you have problems displaying Who's Online, you should disable this option.
- Enable Spider Display
Controls whether spiders are shown as spiders instead of guests on Who's Online. Identification of spiders is controlled via an XML file, which is discussed here.
