Don't know about locking a PowerPoint document, but how about turning it into a PDF document, one slide per page? Then people can page through it in page-per-screen mode as if it were a slide presentation, and it's also tamper-proof.
My difficulty at the moment is the notes pages. The content of the actual slides is obviously only a framework supporting the presentation. Given as a live presentation it would have me explaining a lot of stuff on top of the slides, and even some places where elements fly in during the explanation.
However, I may not be able to do it as a live gig at all, and in any case the audience would be limited. I need to be able to present the text as well as the slides online, for people to access as and when they want to. I could try recording it in audio format in real time, but in a way it would be more useful to use the notes field for that.
PowerPoint itself is very good in that way. You can just look at the slides if you want to, or you can open up the notes field and read the detailed explanation. Libre Office isn't playing that game. The position of the notes pages is bizarre, and anyway they're showing up blank.
I've been using printouts from PowerPoint with the notes pages, which are very good as hard copy - slides at the top, and then the programme formats the notes to fit on the rest of the A4 page. That would be excellent as a PDF, but I don't know a way to save in that format.
Actually, I suppose my problem is two-fold. One is working on the presentation at home, without PowerPoint on my computer. To be honest Libre Office isn't cutting it - it's no better than what I was doing, which was just typing into WordPerfect, then swiping that off a memory stick into PowerPoint at work. The other is figuring out how anyone might access the finished presentation once I put it online.
If nearly everyone has the real PowerPoint on their computers, the latter solves itself, really. I'm coming to the conclusion I need to get PowerPoint itself on my own computer though.
Can anyone recommend an inexpensive way of doing that?
