I received an email with your link about 1 month ago. Since that time, I have been logged on to your website for 12-16 hours per day, most everyday. I leave the sound up and go about my day. Active (well, attentive may be a better word!) viewing would be perhaps 1-2 hours per day. My viewing time zones change as I work half time on the east coast of the US and half time in the highlands of Guatemala, but my computer is on Africam from roughly 7:00 AM till 11:00 PM.
You have added immeasurably to my life. A million thanks and kudos for your wonderful work.
