What I always think is great is the feedbacks… There you get a tip, better, reads something about a problem including the given tips. Such a tip can have been something – provided you give the feedback, what happened then… Otherwise tips are super helpful, because if one says for example, you have to put bleach in the tank with diesel nails and afterwards no feedback comes, if it helped ha t. By the way – it does NOT help, except that the engine goes up. So don’t make it, it’s engine-dead! It helps the other victims immensely, if they also experience the result, is actually the basic idea of a knowledge exchange in specialist forums – the other also participate from it. It can be installed an automatic function, the questioner after a few days get mailed the request, whether his request was helpful. Or runs it only like this, negative result They are commented through, positive ones remain pleasantly concealed… I’m only concerned with the basics.
