Gorgeous. I really need to try Flux.

I believe Reddthat federates with everything.

Failing the captcha doesn't mean you lose your user name. I failed a few times. There's a button you can click to generate a new captcha so you can try again.

I've been using SimpleX, and I like it a lot. Very polished and reliable. The company is registered in the UK.

I use Shotwell to organize my photos. It can handle creating folders by date automatically, and allows you to rate and tag. It works well for my needs.

Gorgeous.
