Im coming to this discussion concerning rby / ruby con very late.

Ruby coin was one of the alt coins I started off with - back in the day Dev's of those alts were active in their threads and would answer numerous questions newbies had when setting up wallets and mining scryot based coins.

I still have my ruby coin wallet set up on an external hard drive so if need be I can verify any signed messages from rubgcoin wallet addresses.

(I'm away until Friday, so it won't happen until then)

If rby is indeed the "original" owner, then they wouldn't have any difficulties setting up a node.
