Correct way to report broken link at openiked.org ?

Hello !

I just saw at the startpage of openiked.org, that the link to Posters
is broken (links to http://www.openbsd.org/older.html#posters which is
a 404 Not Found). The startpages of OpenBGPD, OpenNTPD and OpenSMTPD
use only one link and the destination is https://www.openbsdstore.com

Thanks for answers.
