Well i really don't know where to post so i am sorry i am here to ask you a question
In past i tried to join many signature campaign but got no reply from them i just post there and got nothing so i want to know how will we know that we're accepted in signature campaign i saw many people wear the signature and then post there application
how does it really works ?
It's different from every signature campaign. You need to check the thread from time to time to know if the manager accepted you or not. There are times when it will take 1 or 2 days for the manager to update because he wanted to select the quality posters that's why he needs some time. There are some that requires the applicants to wear the signature first before applying and there are some that doesn't require them to do so. You just need to look at first the requirements before applying the signature campaign because there are times when the managers specify what ranks can apply in the campaign.
As an additional, you can find some signature campaigns here but most of them are paying tokens and will be paid after their Initial Coin Offering.
