Ben made an appearance at the July 2023 Fedcon in Germany. It's obvious from this image that he's glad to be there.
We watched a video of one of his presentations at the con posted on Youtube.
Search Youtube for "fedcon 2023 ben browder" to find the video (our news feed doesn't support links (sorry). There are a number of vids there. Claudia Black also joined Ben for a joint presentation.
