I installed my FvFWQ and went to check it out and met a couple players there (at least one is from Brazil -- not certain where the server is).
I told them to try our server, but they don't seem to know a lot about standard quake.
Anyway, here is their forum: http://tfcustom.gurubb.com/viewtopic.php?t=22
the server is: phoenixlabs.org:27504
Here's the server status: http://www.gameaholic.com/serverstatus/ ... 0.194.178/
Of course, you have to have a QuakeWorld client to connect, though apparently Darkplaces can connect to either type of server. You also have to download the FVFQW mod, which a QW client should do automatically, though it's a bit slow.... I don't know of any place to DL it online; there used to be a site, but it's dead now.
The server is different from ours, and has some bugs and other odd stuff. Check it out if you want, or go and try to recruit players for our server
