Re: conlang survey

I'm interested in this conlang survey that went around recently.  What I'm
wondering is what sorts of questions ought to be asked, specifically those
that are multiple-choice type questions.

I've got quite a few of my own conlangs to catalog, so I'm starting there.
A few obvious ones jump out at me, like basic word order (VSO, etc),
modifier before or after root, nouns inflected for case, number, tense, etc,
presence of inherent genders, etc, but I'm sure I'm missing a bunch.

Any ideas?
