I have modem, and set my max uploads to 3 at a time, with 10 per person. I vary the upload speed between 2 and 5 Kb, it never seems to exceed 3 anyway. It's not that someone asks for more than 3, because then they are "cued" (which I love to see). It must be that there's not enough bandwidth at the time for 3 uploads?
I've never seen the Locations column behave the way Birdy says. It never says anything. That answer doesn't work. (version 4.12.6). Thanks for answering.
