Please tell, why would slotlady as an example, with 82,000 subscribers on youtube, most probably monetised, so she is getting paid for her time and effort, come to a forum that has 115 daily visitors plus one little boy dominating everything?
Victor, I seriously doubt your wish for a bet selection only forum will grow legs, how many do you think would actively participate, as opposed to simply digesting the work of others. It's a chat board, not a successful one at present or nothing. That is the stark reality, the best you could possible do, is put the cild to bed, hopefully the board picks up to where is once was, and introduce banner ads.
Or open up your own youtube channel, once you have x number of subscribers you could monetised it, so would be earning when people watched, it would take something special because many are already ahead of the pack.
