Hi all, I came across this forum just by accident and I found this post quite interesting.
Copyright is a very complex issue, I know, I have been involved in litigation before and it cost me a lot of $$$$$$$$
In the end because I was furious and made some rather honest (but not well thought out comments publicly), I ended up having to PAY the other party damages !
Just be careful what you post on a public forum about anyone, it could bite you on the BUM big time.
They may be in the wrong however it could cost you in the end.
I had a look at the sites you guy's are discussing (google is a wonderful thing) and I cannot find anywhere that mentions any affiliation to the other breeders therefore by defult there is no association.
With regards to copyright if it's different by at least 25% there is nothing you can do, from what I have read in the T&C's on both sites there is a difference, not great but it is there.
IMO go forward and live your life, karma is a wonderful thing.
Steve.
