I understand… Personally, I think it would be a great way for any webmaster to get their players to start spending a little more cash in the name of prizes. I also think it will be better if there are more players – which is why I am doing this.
PLUS – for forum-based sites – it is a great way to send players to a contest on another site all the while keeping those players tagged to you.
However – More to your point….
I just don’t have the time to create another complete site just for this type of thing, though. 
I already spend way too much time on my current sites, including AGD which takes up most of my time.
Would it help to put up links such as….
‘You came from: Games & Casino Website’ (linked back, of course)
or anything else like that which would help to convince you and others to participate?
Thanks.

PS – give me any ideas that I might be able to implement that would make this worthwhile to you specifically (that goes for anyone, BTW, not just Dom)
