I need a little help in registering in cosblog and cosplayer archive (cos.jp)

I hope I have the right site xD
Go here: http://www.cosp.jp/site.aspx
Click the first button.
The fields are as follows:
Name of site
Site URL
I think the next one is loose site url... I dunno, I'm still learning. Maybe transferable? *headdesk*
E-mail (Hotmal is not usable)
Your introduction
Profile picture
Banner picture
The menu on the side says category registration. Then the two buttons are with which you choose.
This next part I don't understand. I know it says site contents, but then it says something about including adults next to the check box.
User ID
Password

It seems to me that this form I described is for cosplayers, though I could be wrong. But the other options seems to be for a business or something. I dunno. Hope I at least helped ><
