Pligg registration problem

I found some Pligg sites, but when try to register get the error "The passwords provided do not match". Is that some kind of problem with the Pligg ? Example sites below:
vuetu . com
sootheo . com
prankfo . com

May be they are not allowing you register at the moment ...

But before submitting your website to these social bookmarking
website make sure that they will provide you some value in
long run ... or they can give negative effect to your website too.

This is how we select our Top Social Bookmarking Websites, just
wanted to help you ...
