We use a small command line tool called crmail to auto-generate code review email from shelveset. I find the whole process very helpful and thought I'd share the process and the tool (which has some really cool features).
Ok they just click on the email links. Since mostly these are managers what more do you expect out of them? Real devs will stick with firing up tfpt command line :)
Self help is the best help :), download the sources from here and enjoy. Buck Hodges post on the direct link URLs would help you in case you want to modify the sources to do more.
