Pretty soon things are going to change here on the Habitable Zone..
We'll have to go to the new ecosystem at HZ.net before you know it. Not long ago, our uber-moderator and Keeper of the Server mentioned that the time of transition is near. Like a month.
So, if you've not registered at the new site, nor become familiar with its many features, I encourage you do so soon. Things may change quickly, the conversation here has been lively, and I hope for a smooth transition to the new site.
