and let us know what terms/definitions should be added/changed..
Probably the most important items I see as missing are ones related to
voting: in particular the concept of binding votes, and lazy consensus.
In Jakarta, these can be inferred from
http://jakarta.apache.org/site/decisions.html, but a more direct
definition would probably be better. I actually would recommend that
this glossary goes a bit further and defines vote and veto as both imply
specific obligations that may not be obvious to someone not familiar
with the ASF.
