Playing with the new group limit I was joining all the viewer related groups I found. The Singularity group is one I joined in the process. The other day that got me a notice that a new version of the Singularity Viewer is out. I’ve never used the viewer. For that matter I’ve never heard about it. It is not in the TPV Directory. But, I’m curious so I wanted to try it. I have an avatar just for testing viewers not in the TPV Directory.
The viewer’s web site is, of course, Singularity Viewer. It is a nice looking site. They have a knowledgebase, download, forum, and a link to the Github for the source code. The forum appears to be a Google Group, not what I think of as a forum.
