plugrush. Reciprocal link is a link between two sites. You link to them, they link to you. Most will fool you to link to them on your home page (usually it has highest rank) and they would link to you on a new page where the infos about your site is and that kind of page has no rank unless you and /or others start linking to it. Not followed links are there to avoid spam, in a way. They tell search engines not to follow links on that page.
