I was just considering whether I should be using Semantic Forms as a means of building structured, queryable discussion pages when I stumbled on your promising extension! That was a welcome surprise. A few questions and comments:
- As can be seen on your own test page (http://www.bestpracticeswiki.net/view/Test_page), the user icon appears to be broken. Apparently, a default icon should be added to Template:Comment.
- The first time I tried, no comments were submitted even if new pages in the Comments namespace were created. I suspect that this may have something to do with the extension not being on friendly terms with internal links or other types of syntax.
- Once a comment is submitted, the page appears to be reloading forever. If you refresh the page, however, the comments does appear to have been added.
- Should this extension be regarded as the successor to Extension:SMWCollaboration (also listed here)? The description is similar, but much of the documentation was added a couple of months later (in March this year).
- What about subject headings? Can the rating option be switched off?
