Here are plugins I thought would be neat on talkgroup, as I was researching for another project (some of these are already on):
- solved
- canned replies
- calendar
- data explorer
- sitemap
- tooltips
- topic voting
- checklist
- assign
- saved search
Major updates, so I added some plugins for the build; interesting aside: Discourse git clones plugins and then builds it all together and compiles assets so the site is relatively fast compared to on the fly rendering.
Anyhow, all the plugins I listed above are added, except “sitemap”. Folks were complaining about issues with it, and it isn’t something I feel strongly about. Honestly, search engines can go fuck themselves, I’m not worried. 
The checklist plugin wasn’t working, so I dug around and I installed an older version, which provided the basis of the current one. Then I had to rebuild the site. Anyhow, checkboxes work now.
[*] See!
If your boxes don’t check, re-save the post. That ought to do it.
