DCC N-scale

I will be investing in a DCC system for an N-scale layout and would like to eventually expand to sound. Currently I am focussed on getting the layout running for multiple opperators. My question is there a webring or, site, forum specificaly for DCC in N-scale?

Thanks much.

P.S. Never, ever take down the old pike for bigger and better without having something to run.
