It can take awhile. I applied with my forums and it took a couple of weeks before i got the phone call
I think about 2 weeks is the minimum....but who knows how long it actually takes...they are not as quick as google.
I don't think they are still accepting publishers, but IDK. I haven't heard of anyonr getting in for months now.
I applied when beta first opened, and a few weeks later got an email saying I had been accepted. My friend applied a few months ago, and he still hasn't even gotten an email/phone call about his application status...
I was rejected a while back with my arcade site. It took about 2 months for them to reply. Now that my arcade a lot larger I applied again last week. I hope I get in.
