This will give you an advanced pagination to distribute your link-juice more evenly across your paginated paged. It also provides a better choice of navigation to the user to explore and find your content.
You can turn the pagination on/off separately for:
<ul>
<li>homepage</li>
<li>search results</li>
<li>category archives</li>
<li>date archives</li>
<li>tag archives</li>
<li>author archives</li>
</ul>
Or implement it directly into your theme using <code><?php the_wp_lopa('pages_below'); ?></code>.
You can also choose if you want it to be displayed before and/or after the loop content.
The plugin is currently available in English and German. If you want to help translate it, just write me an email. Help is much appreciated!

Logarithmic Pagination

This plugin inserts pagination to your blog, archives and search results based on logarithmic calculation for a more evenly distributed link-juice.

A simple, lightweight WordPress plugin to completely disable author archives/pages (regardless of whether the corresponding author really exists) and make the web server return status code 404 (‘Not Found’) instead. Related links will also be either disabled or completely removed.
The plugin does not require any configuration. Once activated, it will start doing its job.

Disable Author Archives

Works!

Disable Author Archives completely removes author archives and makes the web server return status code 404 ('Not Found') instead.
