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.

Smart Archives Reloaded allows you to display a list of posts grouped by year and month. It also provides several interesting navigation elements.
Format list:
<ul>
<li>list = a list of posts grouped by month</li>
<li>block = a compact block of links to year and date archive pages</li>
<li>menu = a two-level menu with links to year and date archive pages</li>
<li>both = block + list (<a href="http://scribu.net/archive" rel="nofollow ugc">example</a>)</li>
<li>fancy = menu + list + JavaScript (<a href="http://www.conceptfusion.co.nz/archive" rel="nofollow ugc">example</a>)</li>
</ul>
