Asking a question:

How to change the language of a website?

Hello, during installation I selected the wrong language. Now I want to 
change the language of my website to english. When I change the settings 
it doesn't work as expected. The error message says: Language 'english' 
does not exist! I checked that the english extension is installed.

Thanks for your help.

New video extension

Hello, I made a new video extension. Its aim is to play videos without 
external services and without tracking cookies. The file formats MP4 and 
OGG are supported at the moment. I would like to know which file formats 
people use and what more I can do to make the extension better.

Let me know what you think. Any comments are welcome.
