On October 4, Bill will be teaching a Vim class based on his recent St. Louis Perl Mongers talk. (I guess that makes this the Ultimate Edition with Extra Flair or something.) If you want to know more about the super-cool stuff you can do in Vim, you should take this class.
On September 27, I'll be teaching a class on vi basics. If you are still one of those people wondering why any of us would actually like using vi of any sort, this class is for you.
More information can be found over at the Computer Room.
Sorry for the shameless plug! (Although if I apologize, does that make it a "shameful plug"? That has always confused me. :-)
