I'm working on a mac laptop computer,

When I go to https://preview-en.bikebike.org/conferences/

I just stuck strolling through the map (zooming in and out)

I am unable to scroll down to see the rest of the content, (attached screen shot)

my fix is to change the zoom on the whole page to make the map smaller, so I can click on the other sections of the web page. But this might not be obvious to everyone. 

The registration button is all the way at the bottom of the conference text. It's not obvious at all. It should likely be on the first view of the webpage.

Maybe Bug:

I added a workshop, and added my org. But I do not see my workshop nor do I see my org on the map.

Does it take a while?
