Super League bosses are to implement major changes to the salary cap in a bid to prevent clubs over-spending.
They have also agreed to use more homegrown talent and stage another round of games in Cardiff to build on the first Millennium Magic weekend.
The 12 clubs will use the pro-active salary cap currently used in Australia.
It will calculate clubs' salary cap positions at the start of and during the season, with signings only allowed if they have room under the cap.
606: DEBATE
RFL chief operating officer Nigel Wood said: "The current salary cap has served the game well but it has a number of drawbacks which we aim to put right under these changes.
"At the moment, it is retrospective and a club breaching the salary cap cannot be dealt with until the following season.
"The clubs and fans thoroughly enjoyed the day and our aim is to make next year's event even bigger and better"
"The new system, which is similar to the proven system in the NRL in Australia is 'live' and means a club can no longer breach the salary cap by miscalculation or mismanagement."
Last year, Wigan and Bradford were both docked two points after being found guilty of breaching the salary cap in 2005.
Hull and St Helens were both fined for minor breaches and Wakefield and Castleford received cautions.
The League have yet to reveal whether any clubs broke the salary-cap rules in 2006.
Clubs recognised a need to provide a bigger pool of talent for Great Britain in their decision to ratify proposals for a "homegrown player" rule.
From next year, clubs must include at least five players who have either come through their academy or are aged under 21 in their 25-strong squads.
The clubs agreed to repeat the Millennium Magic event on the first Bank Holiday in May, with fixtures again based on derbies wherever possible.
An aggregate crowd of 58,831 watched the six matches at the Millennium Stadium last month and fans gave the event a big thumbs-up in a recent poll.
Wood added: "The clubs and fans thoroughly enjoyed the day and our aim is to make next year's event even bigger and better."
