I edited the Sixam landing site but so far not a lot of alien partying going on yet.
I tried to post this last night and I got a message that it would be posted after it was reviewed... ? It never posted as far as I could tell, so hope this isn't a double post!
I added sleeping quarters, restrooms, BBQ grill, everything an alien needs for a party!
