Dead links in the New Member sidebar

I've noticed that the "contact suggestions page" link in the New Member sidebar links to libranet.de/suggest, a 404 page; whereas the actual suggestions page is libranet.de/contact/suggestion… The "support@libranet.de" link also goes to a 404, perhaps the interface to follow a user by link has changed places.

There are also several dead links and broken embeds in the Friendica Walkthrough - maybe that's an upstream issue.
