Research that needs to be done / research ideas.

[Koen G]

I received an email from someone asking how they could contribute to Voynich research. I thought for a bit, but didn't find it easy to come up with an answer. Sure, I'd like someone to find better matches for the month names handwriting, but that's an extremely specialized and tricky task that we kind of crashed on ourselves. In other words, whenever I think "someone should do this", it's because the research requires expertise that I don't have.

But maybe some of you guys have more inspiration? If someone wants to contribute to the research, what are things they can do? More generally, what are research topics that you can think of that you'd like to see anyone explore?
