3 days ago i aplay to helper of cubecraft but i havent recieved any email , when i will know if im accepted or not ?
Couldn't have said it better myself.You don't meet the minimum requirements for helper (100 handled reports, 200 messages (Good feedback, suggestions etc.)
Also, it takes between 2-4 weeks for your helper app to get checked. If you haven't been sent a reply on the forums that you've been accepted for a helper interview, then you've been denied. (One of those reasons being that you don't have the requirements)
