Nvu Tutorial version 0.4 is now available from the usual location or via software update process described in the link. Please remember this is my crappy web server so in case you get some errors try again in a few minutes.
Changes for 0.4 include better explanations for generic font-family, uploading a web page, publishing a web page, etc. For complete change log, read here.
PS: If you have any problems installing ver0.4, please comment here.
