simple truth is dont invest in online directories or schemes where you don't own the website
invest in your own site to drive traffic to that. A website you own and maintain yourself is the cheapest and probably the best advert you can have
learn how sites work, how they attract your client through Google searches, these types of schemes rely on you not being bothered to learn yourself - thats fine but you are never going to actually drive traffic to YOUR OWN site unless you learn the basics
you can buy a hosting package for a fiver a month and have loads of sites on it that will out perform CCN
if you can't work out how to do it, get your site reworked properly and optimised - its cheaper and better in the long run
look at Spick & Spam that Cleanitup started - got lots of people join up at first with lots of promises but when was the last time you saw it come up in a search?! And if Cleanitup can't make it work with all the people they have on this database - then who will?
