Many of us have lamented the inability to force commenters to register here. I have been looking forward to the new version of MovableType (the software that powers this site) because it includes a comment registration system called TypeKey. Since OrangePolitics.org is a community service written and managed entirely by volunteers, it's obviously important that the software has been free for us to use.
Well that new software was finally released this month, but the free version is now limited to only one author. We currently have about half a dozen authors, and hope to add more someday. So this pricing change present a serious barrier to upgrading. Especially since we hope to syndicate the model of this site for other communities. (ChathamPolitics.org anyone?) With the current version of the software we're using, I can expand this way without limit.
