Certain Gliteratti members are eligible to write advertorials, which pay quite handsomely for every post.

They'll send a mail to the one you registered to Nuffnang if you've been chosen for it. If not, you'll have to try check the Advertorials tab in the Nuffnang page. Note that the due date can be a few days from the notice, or maybe a week. Sometimes you'll have to wait for quite some time before they response to the advertorial proposal you wrote.

Take note that never post up the advertorial up to your blog before they approve it.
On the other note, I find that CPM ads in Nuffnang is more fruitful, if you're not doing well in CPC. CPM pays off in bands. The more bands, the better pay.
I dunno how to explain it in depth, but for easier understanding, it's just like renting a space for the ads to put up there.
From my experience, I can say that foreign ads are more generous in bands while locals can be very stingy, less than RM1 also got!

@ scum_bag, good luck trying Adverlets, most of us here have a hard time to deal with it, much annoying compare to Nuffnang.
The common problem we all faced is they dont pay when you're eligible to do so, and always give excuses to delay it.

Although Nuffnang may be slow, but at least they pay-off nicely.

Earning money on the net is just like any other jobs around, you cant expect to rack in a lot of money in a short period of time. 

was invited but had to turn down.
