Features:
This plugin will show all users currently online, followed by all offline users in italics.
You can click on a user’s name to view all posts by that user.
If you hover the mouse over an offline user’s name it will show you how long ago they were online.

You need javascript enabled for the list to update without refreshing the page.

Changes from version 0.6:
Fixed a "Invalid argument supplied for foreach()" bug

Changes from version 0.5:
1. Opera web browsers will now update the Who’s Online list without a page refresh
2. Version 0.5 required MySql 4.1, I’ve modified the SQL to work on 3.23 on up
3. Database table is created automatically

To install:
1. unpackage into your Wordpress plugin directory
3. activate the plugin and call tms_online_users(); where ever you want the currently online users displayed
