I think it would be helpful to have some pointers to places where people can get definitions of linguistic terminology, to help them understand answers. I try not to use too much technical linguistic terminology, but it is difficult to avoid at times; and the whole point of technical jargon is that it makes it easier to discuss technical issues.
Perhaps we should have an FAQ entry that points to places (such as Wikipedia, Glottopedia, IPA, WALS, Popular Lingusitics, SIL lexicon of linguistics, etc, etc) so that people can look up unfamiliar terms?
