This hasn't really been settled on but :
There will only be one list, this list will contain all servers. The open.mp team is?not planning on monetizing the project in any way, but IF they do : it would probably be by selling "boosts". "Boosts" would put your server at the top of the list, and as other people purchase server boosts your server will slowly move down the list.
Pricing will certainly be a lot lower than a hosted tab spot in SA-MP.
