Hi John thanks for the suggestion, yes I have. The rationale is based on ethos more than functionality, so there are no plans to develop moderation of forums on Core Moodle. The Moodle rationale is that a clear code of conduct, and issuing of warnings/removal of learners breaching this should be sufficient. I see where they are coming from, but I still wonder if anybody has managed to achieve moderation through particular plugins. I haven't come across anything on the Moodle forums in this regard.
