I have saved the entire webpage to my local machine. If it goes away, there will still be a copy available.
No worries ;)
He's written some other interesting stuff I'm going to scope out.
The best way to save is copy, paste to a file and save, in my case an .rtfd. It will copy photos and I can paste all of it to my text editor, edit if I need to, then save in the afore-mentioned format because there are graphics in it. Otherwise it will just save as .rtf.
If you are running Windows, I don't know where they are with the process now. I used to be able to save web pages in the .html format with my older version.
Excellent!
