Yep - found that one also, it's like the only one out there i think
It's crazy, the contrast of available article directories in English and Dutch is just abnormal.
For non-competitive phrases article directories have helped me greatly in link building and combined with some thought out on page optimization, rankings where very good for me.
Link building - without article directories, getting links from Dutch sites is much harder this way
And thanks for the suggestion Ferre!
P.S. Know of any Dutch active SEO forums perhaps?
