I know I haven't been a BBB member for very long (I was a lurker for a long time!!), but I think a "Cleaning" forum would be great. There are so many cleaning issues: how to get stains or smells out of clothes or linens, kitchen messes, house-related cleaning, etc. It would be a great place for questions or for cleaning tips in general. Maybe even a sticky at the beginning of it, with cleaning FAQs or How-To's or something...

Anyway, just a thought.
