Hi guys, so as the title says i have applied to 3 sig camping and all of them got rejected i don't get it ? why am getting rejected ?
There are newbies just joined the forum and have 8 or less post counts and they are getting accepted over me

You are just a newbie and don't be disheartened. You shouldn't be applying for campaigns so soon as they mainly accept Member ranks or higher. Your post quality is not up to the mark as most of your posts contain few words and smileys while some posts are constructive.
Till you don't at least become a Member, you can continue contributing to the community and even improve your post quality and knowledge. I believe that learning about Mining at this stage is good as when your rank increases, you will earn even more for your posts.
Maybe he just want his stay in this furom to be worthfull which is good since he can earn little money by posting here in furom but he must consider all things before doing that its because campaign managers want quality poster and not those posting spam just to and shitty one's, and also it is very advisable for those starter that they should do some right things here in furom and brought some very nice post quality since it can be their reference when applying in good campaigns in near future.
