It's not hard to find stuff on GT...ya' just have to now how and where to look which can be a little harder. :)
Lisa's catalog of lessons: http://www.guitartricks.com/instructor.php?input=311296 as posted above by Jon and this updated a year and a half ago, http://www.guitartricks.com/forum/showthread.php?t=28291&page=1&pp=7&highlight=finger+picking+level and this, http://www.guitartricks.com/forum/showthread.php?t=37695&page=1&pp=7&highlight=missing+lessons , a previous discussion about elusive fingerpicking lessons...apparently an issue that hasn't been fully worked out yet.
I hope this, Jon's and Christopher's posts help.
