I have found a web directory crediblelink.com, however there is no submit button to add URL's.?

What could be the reason? Is it a way to make your directory authentic.
@@ Jake but my point is if they are new in the market then why they are not accepting submissions. Is there any SEO strategy they have opted.
And i want my site to get listed before the site become too expensive to get listed.

They may not be accepting submissions, this Indian site is just 3 weeks old, probably getting an insignificant amount of visitors and not worth being listed on, for now.
