I clicked on Help in the top panel, then chose Chat. That would have accomplished the same thing that simply clicking on Chat did. The Chat support function is a good example of how they are doing that. I was curious about was whether the conflicts between Nautilus and Evolution had been solved. The answer was yes, but I am still not running both of them on a regular basis.
Evolution is currently available only from daily snapshots.
That means you may have a stable version one day, update it via Red Carpet the next, and lose everything you had saved and maybe not even be able to run it at all until the next day's snapshot. Before I could try Evolution, I had to install it. I had assumed that it would be there after the installation process, but I couldn't find it on any of the Programs submenus. I was instructed to open Red Carpet again and click on Subscribed Channels. After selecting Evolution, I saw options for installing, removing, and updating the software.
