Do we continue with this theme, to allow comments for those logged in?
Yes, it seems like the best option.
No, there are other options that I will explain in the next question.
What are our other options, while staying on livejournal?
Should we suck it up and pay to move to dreamwidth and import the community?
Yes, because it is the way to get it back to the way it was.
No, because the community is largely based on livejournal.
