There are ghosts who wander through from time to time. Geoff (the owner) is in the midst of an overhaul that he hopes will revitalize the site.
Good to see somebody else posting here. Put up some interesting topics, and I'm sure you'll get comments.
And the regulars can be quite helpful, too.
I notice Mary replied to your post in the general discussions.
Frankly, the people who were most active on the site all took big hits during the recession and are busy trying to re-establish themselves.
Also, if you're on FB, "like" the Muse Cube page and you'll get notifications of work listings, etc., in your feed.
