I actually meant you PM them the link every time they request to be added to the whitelist to save them trawling through the thread for it, which most of them won't unless they've been reading until now, so won't be aware, but meh, whatever. Server is quiet at this time anyway.
I made a floating island (getting the grass to grow on it involved building a temporary land bridge/stairway from dirt to the mainland):
World Hole cross-sectioned my castle:
And I accidentalied Scraby's Canon while waiting for the grass to grow. Sorry man.
I fixed it though, don't worry. 
And before you ask I recently set up traps for the mobs that follow me off the beach into my castle - Been gathering lots of gunpowder that way.
