http://xtremecarforum.com/auto-news-around-web/ I add'd some RSS Feeds of auto news sites to make threads to offer some quick information for the people on the site. How will that effect my PR, SERPS or anything like that? Or will it just do nothing and everything will be okay?
If anything, the extra RSS feed will get some interested clickers and increase your traffic. I'm sure any effect will be positive.
All those links on your auto forum site aren't going to help you, especially the 4 footer links. I'd nofollow those asap before you get penalized,
