Freecycle can be awesome, or horrible depending on the
local "moderator".
I used to use it a lot, then we got a moderator that started rejecting 1/2 my posts. Ok, on one post where I was offering free
pond plants and made a comment that I would also be willing to trade for other
pond related items, I can maybe see rejecting that one. But she also reject a post where I was looking for something and stated that I'd be willing to travel "anywhere" to pick it up, she rejected it because I didn't list where "specifically" I'd be willing to drive. Pretty soon hardly anyone was posting anymore so I quit.
But as long as you don't have that type of situation, it can be a wonderful.
My opinions are barely worth the paper they are written on here, but hopefully they can spark some new ideas, or at least a different train of thought
