I don't really know what's happening, but I, too, get the feeling that Atlasia's potentially in terminal decline.
The dual dissolution worked well for a short while, in giving the current membership a shot in the arm, but we've failed to attract new members, and it's looking entirely possible we may have a Senate election contested by only one or two members (sorry for my part in creating a vacany, BTW
).
For my part, I've been finding myself fairly busy with "real life" as of late. I was considering leaving the forum, but I figured leaving Atlasia might work instead... we'll see.
