I watched the demo page without a problem.
Then I clicked on “register a new account” => this took 5 minutes to display the registering dialog…
Anyway, I went to the end and received the confirmation link by mail => clicked on it, then waited several
minutes again and it goes right.
Then, I went to my account page, checked my status and well done ! It’s a success !
But…I clicked on the “my site” button => waiting, waiting, still waiting again. So, I closed eveything and went away.
