I think the Buy, Swap, Sell stuff depends on how big your community is too. We have a reasonably small community and our BSS board is awesome. I've made $70 in the last few days. Hoping to make $103 for the money saving challenge this fortnight

The Organised Housewife has a 52 week decluttering challenge starting this week. I get her emails, and really love them.
The first one is reasonably simple - declutter your notice/mood/inspiration board.
