Does anyone have a URL for a website that has info on home composting?

I have been composting my own stuff since I mved into my new house last
July

There was a LOT of biomass to be dumped and since then there has been all
sorts a=of kitchen scraps in there aswell....But it simply isn;t breaking
down....I would have thought that by now I woudl have something I could use
on the garden....But none of it is...

I really think that it hasn't worked right because I have done something
wrong...
I didn't have any heat in it over the winter either....

Can anyone help me?

(Also....Can I put ANYTHING in a comport heap/bin?
