I don't have any evidence for this, but i believe a deal was done with American Rugby News for them to release any news and for the AMNRL website to not compete with them.
That makes sense to me. The League section of American Rugby News spreads the word through the Rugby community. It's a good mutual arrangement.
As fans of the AMNRL we should check out the league section of ARN as often as possible. The more we use it the more they will be keen to print League stories, and the more stories they print the more American Rugby fans get to hear about League.
