This is a small task which anybody may contribute to.
There is already such a page at http://alain.knaff.lu/LglMap/
However, while this page shows how to find the LGL, what is missing is how to find the meeting room.
Task: Use the existing page as a starting point, and add details where the meeting room is (entry opposite of the pub "Um Bierg")
We have already some items, such as google-map screenshots: http://alain.knaff.lu/LglMap/work/
