Well, the name says it all. Do not hesitate to apply. There aren't many rules and they are more like guidelines. I don't expect millions of members and don't ask members to add hips of MOCs. But more MOCers than I sought allready build a 5-wide car (fitting a minifig or not). So, I thought it would be nice to gather those in a group because I think there is a lot of potential in 5-wides.
