email: happybeing
UPDATE: @Viv FYI, after shutting down and restarting my PC (so different IP now)…
Browser can’t connect (didn’t wait for an error as I realised I need to update my IP)
Go to the update IP link for my original invitation, I just get “Wait…”
Tried again, same thing “Wait…”
Being impatient I requested a new invite, and this successfully updated my IP and I can now access safe://yvette
I can also log into the account I created with the first invite
Now trying safechat.jam 
I’ve now loaded all these test websites (grabbed from the above posts):
