Because, Newbies have no knowledge about the campaign, If they directed towards campaign, They even don't know what they are doing,
& they never ever try to learn these things,
That's why they are not acceptable.
They need to learn about forum.
This is true. Thanks! That’s why newbie like me cannot join yet to some campaign because we jjust need more time to read and learn how its works, and what is this all about.
