I've used Freecycle for quite a while now and given loads of stuff away and I have received a few things too. When giving stuff away, I only tend to email the person who I intend to give the stuff too, as another poster said you can get loads of enquiries. How I work it though is, I won't necessarily give it it the first person to respond, but tend to wait a day and then make a decision. I also decide who to give it to by how they respond. Sometimes I get an email saying Hi I want it, others are far more polite and state what they need the item for, in my mind manners cost nothing and they might be getting something they want for nothing more than the petrol to pick it up. I am sure you are anyway, but always respond politely and don't seem too desperate or needy, again I have had responses, that were in my opinion way OTT :). As already stated, you can put on a wanted post, I have done that for a video recorder and got one. Good luck, I hope you get your bookcase, the system does work and I think it is great to keep stuff out of landfill.
