Ask.wireshark.org runs on OSQA, which is no longer maintained or supported. Over time features such as external authentication and spam filtering have degraded. It depends on an old, EOLed version of Django. It also fills an important role in supporting Wireshark by providing a quick and easy way for users and developers to get answers.
I would like to migrate to a different platform before OSQA degrades even further. I will post some options for a future home below. Please add votes, comments, and other options as needed.
UPDATE March 31: I just ran across this discussion on Ask Fedora. They're having issues maintaining ASKBOT, but Evgeny Fadeev (ASKBOT's main developer) seems to want to help. One person suggested moving to Stack Exchange, but other comments there roughly echo the SE comments below.
We should upgrade to Mailman 3 and use HyperKitty. We're currently managing the Wireshark mailing lists using Mailman 2 and archiving them using MHonArc. HyperKitty is a modern archiver that allows voting, but it appears to be missing other features that make Q&A sites useful, such as the ability to accept a particular answer.
