This plugin adds a hidden “inverted” checkbox to your forms to prevent bots from submitting them.
<ul>
<li>Adds support for Contact Form 7 via shortcode <code>[ica_checkbox]</code></li>
<li>Adds JavaScript-based hidden checkbox to regular forms in the footer</li>
<li>Blocks form submission if the checkbox is unchecked or missing (typical behavior for bots)</li>
</ul>

Inverted Checkbox Antispam

Simple spam protection using an inverted checkbox. Compatible with Contact Form 7 and custom HTML forms.

Tired of regularly logging in and clicking the “Remember me” checkbox? No more. With this plugin, once 
you have logged in and until you voluntarily log out, your blog will remember you.
The ‘Remember Me’ checkbox on the login form will be always checked, and instead of logging you in for 14 days, the expiration is set to one year.
