This all should absolutely be in english! It is Very frustrating to constantly try and find answers using the google translator! The english does not have to be perfect, don't worry about making mistakes and use german word for something if you simply don't know it in english and google translator can't help! Even very poor english is much much better than german. Imagine it this way, if it was all in Japan how likely would it be to attaract others around world (germany including)? The same goes for this board, your playground should be the whole world, not just germany. I'm very sure that switching to english would attaract a lot more business for Marotronics too.
There are a lot of enthusiasts around the world willing to help. That being said, I have shot 77gigabytes of material of me making my robot. Soldering of each and everypart, preparing the chasis, putting electronics and chasis together etc. I have no idea when I get it all edited, lots of video and I'm not familiar with editing.. But it will be all in english and will help others to put together the whole thing from start to finetuning the parameters.
Edit: So it's not oneway street. English will allow also a lot of people to help Germans. The more people we have who can provide help, comments, code etc the better for all!
