Here is a basic outline of my school. 1. Around 400 devices. 2. Classes change each hour so probably within the first 5 minutes of class, the students would be logging in. Most teacher machines would already be logged in and just staying on. 3. Even though there are 400 devices, I would guess there are around 100 students logging in each hour within those first five minutes of class. I think that would be a typical scenario. Just looking for a suggestion to start with. Thank you very much. -- Scott Mayo Mayo's Pioneer Seeds PH: 573-568-3235 CE: 573-614-2138
