MCR01 Passion-The website

After 4 years of existence, the forum MCR01 Passion has become a wealth of shared knowledge from more than 200 members totalling to more than 2,300 messages posted on more than 300 subjects. As the forum had grown very large is was time to put all the information gathered into a more accessible way, so the MCR01 Passion website was launched and offers articles about the construction of specific parts of the MCR based on the information gathered in the forum.
