The forum, like everything in life, must evolve. What would not be normal is that any user who has an account only uses it to participate in signature campaigns and when there are no campaigns they do not contribute to the forum, they have the same opportunities as other users who are "always" here. I understand that we all have things to do in life, family, work... But we must be aware that signature campaigns, after all, are a privilege, and that this privilege cannot be shared in the same way for one type of user as for others.
Freemind thanks for encouraging users with +1. And good answers.
This is how we (all of us) improve the forum
One day later, karma become most important part for user get criteria for participating in campaign but all decision depend on each manager behind some user get less karma points but get accept on their campaign.
Most of all bounty manager of signature campaign here from bitcointalk forum, seems they will adopt the same way have adopt early in bitcointalk about merit requirement needed and in altcoinstalk forum they will use with karma point minimum to get participants in signature or campaign bounties.
I think that sooner or later it will be like this, but that does not mean that all managers make the same decision or use the same criteria in their campaigns. It may be staggered, but time will tell.
