Our sim neighbor Leaf Shermer has been absent from Second Life for about two years now. Her reasons are personal. I don't understand them, but I respect her decision to stay out of world-- and I REALLY respect her for keeping her sims in SL while she has been away.
The other day Leaf left a message for me, saying her sims will be disappearing within the next few weeks. That means we will say goodbye to her full sim Eccentricity and homesteads Idiosyncrasy, and Whimcentricity, Our homestead Whimsical Mischief, which Leaf has been renting, will go away as well. In this case I know just when it will disappear, for tier for Mischief is due on the 4th of February.
I will especially miss Whimcentricity, where our amazing glaciers live. Perhaps we will relocate them to Whimsy Kaboom.
Do yourself a favor and visit W-C while it's still in world.
