Muppety Puppety

Been watching Muppet Show DVDs with the kids. The episode with Vincent Price was not as I remembered it. I clearly remember him transforming into Guy Lombardo during a skit, and closing the show with "You've Got a Friend." Yet, on the DVD, he transforms into Jack Parnell, and there is no big music number.

Happily, this is 2010, and Muppet Wiki site informs me that my memories were correct. The name "Jack Parnell" was dubbed over "Guy Lombardo", and the musical number was cut.

A question for Tech Writers!

I have a question for all the tech writers on my friend's list, or all the folks in software/process documentation, and related fields.

The set-up is this. I've been a tech writer for about 7 years, but I have absolutely no specific training in the field. I have a generic journalism degree. I sort of drifted into tech writer from general corporate writing. I'm finding myself at a loss because I've had almost no exposure to the software tools used for authoring and documentation.

If I were to enroll in some night classes or continuing education, what software training should I be looking for?
