Take it this is in a different breed from your avator as I thought DCC and RDCC came from Open. Hope I'm correct as I have passed this on to someone else!!
Having looked again on my PC instead of the notepad I think it is a Curly and not a Flattie on the avator (pic very small on Notepad) which means I haven't had duff info, or passed on such. Well done for your Curly RDCC.
