Hey Jack,
Thanks for writing. I will be writing a full post on here with all the details, but at last week's meeting we decided to change the format up a bit. We will still be using the book to an extent, but going forward we're no longer following the book a chapter (or two) at a time... at least not in the manner that we have been.
Instead we've decided to switch to a more question-and-answer format in which we use the meeting as a forum to test each other with questions of various topics, and focusing (to a limited extent) on a particular topic each week.
I'll have to check, but I believe our next meeting will focus on/around chapters 4 & 5 (collections, generics, and serialization).
Hope that answers your question!
