we have been using and demonstrating discover on a 2yr old cheap acer laptop for the last 2 months..
I found the trick was to ensure sims is not open i.e use the discover login directly..takes a lot less resource..
On a seperate note...does anyone know what the parameters of the attendance timeline are i.e cumulative or weekly calculated.
On a final note..discover presented to 20 schools so far.. 95% take up rate..especially useful on identifying behavioural issues by category and location..i.e bullying.
