Thursday mail - summer edition (ongoing).

I won't be updating the blog with content for the rest of the summer - I need a break. But, as requested, I'll leave this Thursday Mail up as the final post until the fall. Feel free to use it like all the other Thursday Mails (i.e., to ask questions, to comment, to share stuff, etc.). I'll be checking in regularly to approve comments (i.e., so they'll be posted) and answer questions. Hopefully others will join the conversations.
