I think the owners of the forums need to get together with those of the independent sites and use this place as the hub. I.e one login and profile for all the sites, but individual site owners can decide on content and moderation etc.
The best thing about RLFANS is that you get different opinions and input from fans of other clubs. On Redvee all you get is Rogues telling you everyone in the world used to support Wigan as a kid and that every young player ever is going to be world class, it really does miss the input from other fans. Individual club sites across all sports are so boring, there is no banter, no humour, just cycles of negativity and activity that mirrors how the team is doing. If the team is losing you get people moaning, if it's winning you get people hugging trees in delight. Twitter is the biggest draw at the moment, it's far easier to post quick thoughts on.
