I haven't registered yet! But i am going to do. The thing is i only have one blog and if i insert mangga ads o my blog, i will lose my glittery status from nuffnang. So i don't know if i want to create my second blog. If i did, then i can see mangga ads' performance compared to some other company like nuffnang, innit, and adverlets. Anyway, why don't you try it first? then let me know. Quite a few advantages of mangga ads apart from it pays lot higher then nuffnang.
