How to make links without increasing the google rating of somebody you don't want to give more credibility to.

Copied here from Making Light, because I didn't know where else to put it.


"Here's the zero-Googlejuice trick. Pretend the pointy brackets are carets.
Standard link: {a href="URL"}link text{/a}
Link with rollover text: {a href="URL" title="title text"}link text{/a}
Zero-Googlejuice link: {a href="URL" rel="nofollow"}link text{/a}
Zero-Googlejuice link with rollover text: {a href="URL" title="title text" rel="nofollow"}link text{/a}
We have our comment thread set up in such a way that any link posted within a comment automatically has rel="nofollow" inserted. It discourages spammers."
