LOL I suppose I should have guessed the unknown field left was email. The other fields are town, country and nickname. Still who uses mail instead of email for a website ?
The odd thing is it still let me join with 'huh?' in the email address box.
Planet 13 and Planet H2 are fun to walk around in.
However planet7 is impossible to move in, there are no steps from the train to the ground, door ways and steps are too high. I had to use Slide and Fly all the time just to enter and exit the tunnel systems.
