Offensive Security is hosting a series of tutorials related to using the Metasploit framework.
I haven't had the chance to take a look yet...but they sound promising.
These are being released in support of the Hackers for Charity project that Johnny Long is associated with...from the tutorial homepage:
"This free information security training is brought to you in a community effort to promote awareness and raise funds for underprivileged children in East Africa. Through a heart-warming effort by several security professionals, we are proud to present the most complete and in-depth open course about the Metasploit Framework."chalmer
