I don't have a PC at my disposal atm, so I'm using #Friendica on my phone.

That may be the reason why I can't find several basic functions, but I'm probably as bad in navigating menus as I always thought.

How do I add a new contact? How do I set the #language for a post?

And does that #Twitter connector still work nowadays, after e-Loon effectively killed it?

Not for myself btw, I quit that cesspool years ago, but I plan on getting a few users on my own instance once it's operational.
