Hi All,
Just wanted to share the results of some SEO improvements I made to RichmondWiki.org tonight. I modified my skin to use the rel="nofollow" attribute on the Content Actions (edit, discussion, history, etc) and Personal (login, talk, preferences, etc) links on each page. This preserves PageRank and could help your articles rank better in organic search results. Hope it is helpful, and as always feedback is appreciated.
