From April 2005 through December 2006, fans participated in a re-read of Memory, Sorrow and Thorn covering three chapters a week, and then logged on to Tad’s Message Board for in-depth discussion (and bonus occasional silliness breaks). The archives of the discussions are indexed here (with thanks to Firsfron).
As noted on the index page:
SPOILER WARNING
This is a REread, so things that give away the ending might be discussed in every one of these threads.
Do not read if you haven’t finished reading “Memory, Sorrow and Thorn”!
