Expire Comment Links was inspired by <a href="http://yoast.com" rel="nofollow ugc">Joost de Valk</a> 
in an article he wrote called 
<a href="http://www.searchcowboys.com/columns/764" rel="nofollow ugc">Comment links: an experiment</a>. 
It all started when Matt Cutts talked about how Google changed how it handles no 
follow links in his article on 
<a href="http://www.mattcutts.com/blog/pagerank-sculpting/" rel="nofollow ugc">PageRank Sculpting</a>.
No one knows for sure yet if this will be beneficial or not, but for those that 
want to be on the cutting edge and try this experiment for themselves, this 
plugin automates everything.
Requires PHP5.

Have you ever launched a website with search engines blocked because you forgot to switch the privacy settings in your dev environment?
This plugin was developed to remind me to do that. Privacy Notice simply adds a notice in the admin bar if search engines are not enabled. This plugin helps you check yo’self before you wreck yo’self. If the label is orange, change it before you launch that site!
If you’ve turned search engines on, the notice goes away entirely. Never to bother you again if you haven’t deactivated.
There are no settings, and it doesn’t modify your database.
<h3>Arbitrary section</h3>
You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated 
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or 
“installation.” Arbitrary sections will be shown below the built-in sections outlined above.
