Unsure if this would still be useful to you when you’ve already found a solution, but to anyone else who may be curious about commenting systems, the one I personally use is G-Comments by twMat. It works quite well and has been one of my favored community solutions. Can’t say how privacy-oriented it is when it relies on Google services, but for a relatively painless setup that requires no logins for end users & can be extended for purposes beyond mere comments, it’s probably the best one out there (that I know of).
Its main limitation, which is either an issue or a benefit depending on your particular needs, is that the plugin cannot retrieve comments from your form’s sheet; it is only made for submitting them. This works out for me because any comments with spam or unsavory material aren’t immediately displayed to the public, and I can just import the ones I approve of manually (I created a tool for myself to do this, this does not come with G-Comments). It also does not have any infrastructure for styling and displaying imported comments, which is a disadvantage if you just want something to work start to end out of the box - or an advantage if you love tinkering like me.
If you want to see the system in action or try it out yourself, a very customized “start to end” implementation is used in several of my project sites:
-
Devius Ex Machina, for viewers to submit comments about the material like the plugin was originally made for. It additionally takes advantage of the way G-Comments pre-fills answers for tiddler names by extending the same functionality to the submitter’s name if they so choose to fill one in on the website.
- The way the website handles displaying comments through ViewTemplates and styling them is all hand-made and/or cobbled together from other solutions, such as using the kin filter operator by bimlas for recursively counting how many comments and replies to those comments were made under a page.
-
BlinkieWiki, which modified the plugin for users to submit metadata for graphics and suggested webgraphic creators. The metadata submission is accessed by clicking on a graphic in search results and then clicking the top right button that says “Submit metadata for this graphic…”.
- A forewarning that this site is very laggy. It is quite large at >30,000 tiddlers and uses complex filtering from a custom search interface to return results on the fly. It has not been fully optimized for performance yet with all the tricks I know about now.
