I also have noticed this Gillian, if I hit enter in the URL box again.. it does work. Not sure what that is about. I will ask @dizzydiscovery who put it together for me.
I particularly love how your fellow explorers have their own avatars.
The old crew of explorers, hate this kind of thing. Leaving stickers everywhere in derps. I don't do that but like the avatar idea.
EDIT: Should work now @gillianpearce. Lacked an SSL Certificate.
