Get the all seeing eye at
The All Seeing Eye. This is an actual
program not a website so it needs to be installed and so on. It is not hard to use, you just check all the boxes of what you want in your desired server and hit refresh. The dead servers that may not be found by ESF game can be found there. It is like the way you filter servers in ESF but finds more. When you find the right one, double click on it and ESF opens and connects to the server (I think ESF must be closed first). The great thing about this is that it will work with Quake, and
most mods for half life like Counter-Strike, Day of Defeat and TFC etc. I think this is the best way of finding servers but it is up to you.
