Great.
Since you are so numerous, I want to make a kind suggestion that 'each' of you can make a 'small' contribution. It should not take a lot of effort to share some experience regarding BT747 in one page (in German).
If every visitor would write one page, we would have something like 100 pages each day.
I can give editor rights to those that ask. It is also possible for me to put text that I receive in the right location. Use the contact form or the email in the 'About' of the application to leave a message.
