Hello,
I make a little advertisement for a survey about quad line information you may need. Information of any kind including technical tip for building or flying or else.
The survey is written both in French and English language. Maybe if people here are interested, a german version could be done 
The goal of this survey is to create a support place for 4 lines flyers that can not be done with existing media. So i think it can be a good start for 4 lines flyers to express their need.
The survey is done by a french kite friend of mine with all my support. He is very motivited in helping the quad line community. Let's give a check here
there are several decade of responses yet
