One more issue:
Editing a comment of an issue DOES NOT notify any of the related/assigned persons. This setting is not fine, but FireFly seems to have no setting, and likely no respective functionality, for this.
Does anyone know whether this is an installation defect of FireFly or intentionally designed that way? If it is by design, then at least this circumstance must be added to the guideline at: http://pandorawiki.org/Reporting_bugs
Otherwise some people may correct some parts of an original comment, and then wonder why no-one re-acts. If they are aware of how this notification system works, they will instead add a new post (and possibly still edit the old one, to prevent the presence of dangerous false information, or leave the old one for chronological/transparency purposes, and possibly still add a short remark to ignore the old (possibly dangerous) facts and look for later comments).
