(1, 3, 6, 9, 12, 24 months) + exception mark
Ability to set boards or categories as volatile so posts will auto-delete according to the board settings.
For my community, I would like an auto-clean (auto-delete) feature after 30 days so I can keep think clean for that specific category.
If I can go further with this, a feature in settings for both board and sub-board that will set the auto-clean to 1, 3, 9, 12 or 24 months would be absolutely amazing. In super rare cases you might want a discussion to last for more than 1 year for example.
Maybe we can have this auto-clean feature and in the same time we can set exceptions per thread, if we consider that it’s worthy.
