Hi Timothy,

The vm-dev list is here:

  http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/vm-dev

It is not a beginner's list, and your discussion would be welcome there. Either
way, you are not creating "noise" and it is great to see you getting involved.

It is a good idea to use a VM from mirandaband.org, because different VMs may have
different runtime behaviour, and using a runtime environment that matches Eliot's
will prevent confusion.

Strictly speaking, you can build a Cog VM using pretty much any VM that works
with your Squeak4.4 image. So no it is not necessary to use a specific pre-built
image, but it is a very good idea to do so, especially during the time when you
are first learning how to do VM building.

I think Eliot will give you a similar answer, so hopefully he won't mind me stepping
in to answer some of your questions.
