I'll likely go ahead and do at least a couple more tutorials in Acrobat format. I hear a lot of the points about HTML being a great way to do things. I just had a bug in my ear that some folks considered Acrobat format more professional. Personally, the way I'd suggest to handle Acrobat files is to download them to your computer, and open them from there. I'm thinking some HTML tutorials are not done with printing in mind. The pages are too big. Personally, I prefer to print a tutorial so I can see it while I concentrate on doing the work on my screen. I don't like flipping back and forth between screens. Some of the tutorials I've seen are horrendous in that regard.
