Proposal in 'cold storage?'

I got a response from Steve Jackson Games for a proposal I sent them a year ago. The source book called "City Folks", which I sent in a proposal for, has been put in 'cold storage', according to the mass-mailed e-mail I recieved. This means that it and many other projects that are not yet begun will be put aside for the time being while they focus on what is 'in the pipeline'. That's OK. I've got other projects I'd rather work on right now anyway.
