Dear List,

Thank you all for your helpful replies (including a few off list)

It is clear that the person who recommended the book to me was correct, 
and I will continue using it in my GRASS-learning endeavor.

I think I might have got a bit thrown off because the book starts off 
dealing a bit with some sites functions, which I understand are now 
part of the vector functionality, so it got me kind of discouraged 
early on.

However, it seems like it will be worth it to plough ahead with the 
book and deal with grass 5->6 changes as they come; having this list as 
a resource will definitely help with that.

And to Markus Neteler, thank you for responding personally, I 
appreciate your efforts to make a table of changes, and will gladly 
help by contributing any of my comments to you as I continue working 
thorough the book.

It sounds like this is an exciting time to be getting into GRASS, with 
the major upgrade to vector capabilities.  I can already tell this list 
will be a valuable resource that will complement the book and online
