No do follow comments

[cmscritic]

Can someone tell me how to set all comments to nodofollow? I want to discourage spam comments.

I do not personally feel that it discourages spam comments at all. I use askimet for my s9y sites, and it does a great job of catching comments. I also have a number of other spam protector settings that limits comments. - you could, for instance, reject any comment that contains a link.

That being said, you can edit your template's comments.tpl file and add rel="nofollow" to whichever links you want.
