Understood. FWIW, I don't have access to any of this myself. Just trying

That makes sense. I wouldn't say most people using U-Boot are doing it
for toy projects, but I get what you mean. Being a Linux or U-Boot user
may be more anonymizing that declaring that you use Xenomai.

True, this is an old problem. But it's going to have to be solved at
some point. Because it's those very users who depend on Xenomai who are
ultimately going to pay the price if it ceases to be maintainable.
The idea was that by having regular meetings at a proper location,
possibly co-located with another event such as ELC or ELCE, then people
could show up "uncommitted" to an adjunct event. Yet, still, this would
foster at least some form of community around the project.
