I ended up on Piwigo. It’s pretty fully featured and allows you to set up access controls for groups. Also has client apps.

Lol… Well I'm glad someone saw it :D

These are fully stand alone. Downloadable. So not strictly hosted I guess?

Does it need to be “hosted”?

I like both these:

yEd (https://www.yworks.com/products/yed)

Dia Diagrams (http://dia-installer.de)

I think yEd had a free version but closed source.

Lexx is wild. I watched it originally on a pay tv channel that had cut the episodes up into ~25 minute blocks.

I first dropped into late season 2 and occasionally I’d miss an episode.

So, combined with the weird cutting, the no context and the standard Lexx craziness, I had NO idea what was happening. The whole thing was a fever dream. Highly recommend!

I actually think it’s was the best way to watch it first go round! Then, when I came back and do the whole series in order and it was almost as much of a surprise.
