Subject Re: [VOTE] Accept Lucene.Net for incubation
Date Sat, 05 Feb 2011 08:23:05 GMT

Being well over 72 since the vote was initiated, and with 16 positive
votes, 3 of which are binding and no negative or neutral votes, this
vote passes, and is now closed.

Thanks for your participation and for allowing us back into the
Incubator to start next phase of life for Lucene.Net. Further
gratitude goes to our helpful Mentors who are already guiding us in
the needed steps to make this transition.

I look forward to my next post announcing our first release under a new status.

Til then,

>> ==== Groups  ====
>>  * Chris, Prescott, Sergey, and Troy are part of the core development

>> === Alignment ===

>> == Known Risks ==
>> === Orphaned products ===
>> The purpose of this proposal is to recover from the fact that

>> Because we will be coming from the perspective of recovering from
