Why is the participation limited in glossary-building KudoZ?

The purpose of the glossary-building KudoZ is to coordinate the efforts of willing members of the ProZ.com community in building up an authoritative glossary of terms and their translations in many languages and fields. With a focus on the quality of the resulting glossary entries and ample time for submission and selection of answers, it was decided to limit participation to specialists in the field and language pair.
