These postings cover prior seasons as well as current season.  You will find the forum moderators and Glenn himself may refer you to this page so you may read his prior response to your always valued questions.  I liken the 'look-up' of an answer in this digest to that of looking up the definition of a word in the dictionary; the process takes me on a more vast journey than just looking up the one word - I stop along the way to read about all the other words I don't recognize!   I find that enjoyable, I hope you do too.  Read on...

More than one comment by Glenn on a particular subject? I have them bulletized or separated in some way (e.g.  + ~ + ~ + ~ + ~ +);  I've included a synopsis of a question where necessary to set up Glenn's comment.  If a posting was retrieved from the SF_PGE forum archives, I have indicated SF_PGE next to the date.
