Edmond,

Sorry, but given the upcoming OTP release I have been swamped by other 
more urgent duties...  I do not have any answers to your questions at 
this point in time (sorry about that) but I would like to mention that:

  1. We are in the process of creating a PropEr web site where among
     other things there will be PropEr tutorials, examples and FAQ.
     Our intention is to have it ready by the Erlang Factory in London,
     so please be a bit patient.

  2. My talk in London will be about PropEr and what it can do for you:
http://www.erlang-factory.com/conference/London2011/speakers/KostisSagonas

  3. The address you are using does not reach the PropEr users but its
     developers.  We'll set up such a user mailing list once we properly
     announce the first version of our tool -- note that it is currently
     unannounced even though I am aware that it's already being used by
     quite a few companies and many Erlang developers out there.

Best,
Kostis
