For viewing the server status you'll need the Q3plug. This web browser plugin is a rewrite of the popular QPlug/Q2Plug-Plugin by John Carmack, Jack Mathews and Dave Kirsch. Its purpose is to provide information about Q3A/HL/UT servers such as game settings and connected players. Like the original version, Q3Plug features a connect button that can be used to connect to the game directy from the browser. Q3Plug has been tested with Internet Explorer versions 4.0, 5.0, 5.5, 6.0, Netscape Navigator version 4.x and 6.x, Mozilla 0.9.8+, and Opera version 4.0 and 5.01 on Microsoft Windows 98, Windows NT 4.0, Windows 2000 Professional, and Windows XP. Please note, however, that Q3Plug won't work with Windows 95 unless it has been upgraded to Win95B or higher.
