I would start by saying sorry that this post is off topic in replying to an off topic post. Perhaps it should be moved to the main discussion on this campaign.
While bored, i looked over the two examples you provided and along with looking at some of the other notable supportable scripts i made some intersting observations.
I must applaud you and your friend on the persistence in which you champion forking the forum away from main support channel.
You mention that you couldn't or did not know about the q&a tools on the PJO site, that is very much like your stack idea. I assume that you have also looked at the linkedin discussion/support groups?
PJO administration on the Q&A is simple, to my knowledge there has been none apart from the odd self promotion and spam post removed in the early days.
I tried to understand the stack discussions, and got lost (and no i dont need/want instructions on it- thanks) i did however come across the very interesting discussion of wordpress concerns when it was discussed moving the forums to stack.
I will enclose it edited below
Note that we do not handle questions:
not specific to WordPress (even if they happen in its context):
blogging and managing sites in general - try Pro Webmasters
that require professional hands-on involvement:
overly complex and specific things (known as work for me for free)
recovering from hacks and server issues
all of which joomla forums and linked in do.
The other iscussion post on stack that was interesting from drupal (and i understand that the stack drupal area is not recognised by drupal team )
Not in drupal.org : risk of losing contribution means killing drupal.org forums (when they're still used)
Corporate, we don't know how it will turn in the future
No integration with drupal.org
Data will not belong to d.o, though it is CC licensed and available
No 1:1 feature match with the current forums
No single sign on, although OpenID is an option
Possible future migration concerns if we do ever decide to bring it back "in house", although we likely wont.
Division of user accesses looking for support. Some would go to issue queues, some would go to mailing archives, some would go to SE.
Therefore my personal view is that this fork (or apparently your closure suggestion) of this forum is unjustified, there are already plenty of support channels.
Pardon the anagram phrase of horse flogging the dead
