Webcam32 has a free version but the cost to register is only like 30 bucks and gets you free updates forever. You can get to them thru
http://www.webcam32.com but I believe its surveyorcorp.com that owns it. It has all sorts of perks like chat and what not now. One thing to watch with camsites are hotlinkers. They can eat you alive in BW. We got nailed for 1800 one month when I first started a cam. And we had no clue why until we dug for days. Talk about put out. Try to explain in Portugese that you're going to break someones head for hotlinking sometime. lol The old man was livid considering we only made a grand from the site that month.
