Dear tsuwm,

I once was an over-qualified member of a group called Mensa whose founder said that its members were those who, "wanted to have their heads examined" which they had demonstrated no doubt by the very act of having taken 'IQ' tests. Heh heh.

Well though more modest, this seems similar. They are simply looking for those who wish to have their linguistic intuitions examined. If they can't pay in coin of the realm though, perhaps they could offer a linguistic intuition measure in lieu of payment in filthy lucre.
