I just wonder what campaign is really the best campaign to join to.
Of course the best campaign are those that are willing to pay good rates to their participants. However, since they are paying at good rates they only accepts members that have good posting history. Every campaign manager will checked your previous posting history and it you pass their requirements then you are accepted. So I suggest that when you started to join a campaign, try to improved the quality of your post so the next time you apply chances are they will hire you. And as you rank up, your payment will also increase. So at least practice commenting that will contribute to the total discussion and not just post garbage just for the heck of increasing your post count.
