I will be starting to set up new Collectives on XWiki later this week. For the past few months we've had a temporary moratorium on creating new infrastructure on the site due to the website transition. The interim period was way longer than we expected. Apologies for that. I'll clean out the queue this week in the order in which the requests came in over the past few months. Also, if you have been waiting to submit Collective proposals to your Community Groups for new Projects or User Groups, please feel free to move ahead now. The same applies for new Community Groups getting approval from the OGB. I only get involved in this process on the implementation end, and everything you need to know about that is documented here: Collective Life Cycle Process.
