I just updated the wiki page with a number of changes.
I also signed up to teach a class on preupgrade in 2 weeks + 1 day.
I am going to try and mail out updates based on the scheduled classes
tomorrow (monday) and every monday after that.
Please take a look at changes and let me know if you spot anything
further we should be doing, or things that can be tweaked.
