Very cool activity indeed, thanks for the great work! :-)
I've just spent some minutes toying around with it in two VirtualBox
machines, one of them running SoaS strawberry with the other one using
Sebastian's 0.85.1 SoaS snapshot from last week.
The two main things I noticed are:
* there should be some sort of start button to get the quiz started, I felt
quite an adrenaline rush when I started the activity and saw the clock
ticking away immediatedly
* there seems to be quite an issue with syncing collaboration because
initially the activities on both virtual machines were off by maybe half a
second or so but after leaving them running for 10 minutes the difference
had increased to more than 6 seconds.
Bryan also asked me to show the activity to the folks here at the OLE Nepal
offices so if I get any feedback from them I'll forward it to you.
