CTP Daily Challenge
These special promos are for traffic exchange owners who already have incremental surf badges up and running. These are badges which are typically earned for surfing 50, 100, 250 pages etc and they can be claimed by members once a day.
The Daily Challenge is a promotion which also allows traffic exchange owners to get their sites featured on the front page of CTP.
It is very popular with members of CTP Teams because by doing the tasks required by the Challenge they win increasing amounts of XP for their team.
Currently many teams have a policy of always completing the Daily Challenge before they do anything else in order to ensure they get as much XP as possible to improve their team rankings.
