Who can participate in the glossary-building KudoZ (GBK) questions?

Participation in a GBK question, including answering, posting references and grading, is limited during the first 72 hours to site users who (1) Have the corresponding field(s) of expertise among their "speciality" fields. (2) Have the corresponding language pair or the reverse pair among their working ones. (3) Are native in either source or target languages. 

During the "working" phase (questions still open after the first 72-hours period) participation is extended to site users who satisfy the language pair and native language criteria and have the field of expertise among their working ones.

All users can post discussion entries.
