Learning constructed languages - a short survey

[Katxoni]

There's something I could use a little help with, so I'm posting this in every more-or-less relevant place I know of.
Basically, I'm writing a paper on constructed languages as a university assignement, and I'm conducting a short (9 questions) and rather basic survey among people who know a constructed language or have at least tried to learn one at some point. It's all collected anonymously.
So if anybody here could take part in the survey or pass it on to other people, it would help me a lot and be greatly appreciated. The survey is here:
