Summary Update
This build brings activation phrases to allow groups to be joined by searching for ... let's call them cheat codes. :)
We also have a tile view for post categories, which you will see in action as soon as I have created the appropriate images.
Comments can now be marked as public, so they will show up without a login. That's mainly to help SEO, but also because some post categories are public (mainly technical articles) and their comments should be, too.
There are some other tweaks, but you wouldn't be interested in those.
