View source for ETTV:Viewer's Guide

Viewing an ETTV game is as easy as connecting your ET client to the ETTV server. Pay attention that you have the necessary maps / pk3s (like different ETPro folders) in your folders as not all ETTV admins might be so kind to offer downloads.

Normally what you see on ETTV is delayed by a minute or perhaps two, depending on the admin's choice. All chat done on ETTV won't be seen by the game server people (luckily).
