As well as not knowing what a "master" is ...see my last post...it's hard to know why you aren't qualified for a hit. For instance....the Great Hits that are here daily...I am rarely qualified for. They don't look like anything weird or unusual,infact they look pretty normal to me. So,it's hard to understand why I am not qualified.
It's just all about doing random HITs that give you access to more HITs. I don't know which ones they are myself. Just do as many as you can and you will finally qualify for those random numbered qualifications. Most of the time I don't know it until I post it in the forum then I see the random qualifications on there. No idea how I got them.
