Follow/NoFollow questions

[bornstein75]

Hi Guys,

I have been reading Lynns post on"Link Marketing: Pingbacks vs Blog Comments" and she mentions Follow and NoFollow links.

I understand that it's best to place your backlinks on sites that have Follow links as this passes page rank and can help your own sites ranking.

1) I was just wondering if we set up a blog in Wordpress, is it automatically a DoFollow link site?

2) Lynn said she uses a plugin called "• DoFollow WordPress Plugin " Should we use it to make our sites DoFollow sites or is it better to make a NoFollow site?

3) I have installed a plugin which highlights & color codes follow/nofollow links on a website, and I was wondering how do we know by using this plugin if it's worth leaving a link considering some sites have a combination of Follow/NoFollow links.......where should I be looking to see if this site is primarily DoFollow?

4)I have also been adding the rel="nofollow" tag to all my affilate links, so they don't bleed page rank....shoud I be doing this or not?

Thanks.
