Forum:Relative index of timelines

The "Category:Eras" page talks about an attempt to place various eras and timelines into a coherent stream with a numeric reference on various other articles. However, none of those articles seem to have such numbers. Was this attempt abandoned? If not, I'd love to see an article that still has the numbering. If so, then the Category page should be rewritten to remove that system. -- Gousha 04:57, January 21, 2011 (UTC)
