th23

Provide your users and visitors a simple and straight forward contact form.
The modern design is very clear, easy to navigate and with light-weight JS and CSS code. One big benefit is its flexible positioning in pages and posts as a modern style block or classic shortcode.
To keep your website safe, it comes with built in spam and bot protection, by using Akisment and reCaptcha for messages sent by visitors. The plugin is continuously improved and used on live websites since 2012.
th23 Contact is built with some few goals in mind:
<ul>
<li>Simple and straight forward option for user to contact you</li>
<li>Light-weight code basis without overheads and frameworks</li>
<li>Easy to adapt styling to fit any page design and layout</li>
<li>Fight spam and bots without unnecessary hurdles (admittedly it’s a compromise)</li>
</ul>

<h4>Usage</h4>

Alternatively use the <code>[th23-contact]</code> shortcode directly in the source code editor view of a post / page or insert it as a legacy shortcode block.
<h4>NOTE</h4>
The th23 Contact form block and / or shortcode can only be used once per post / page!
Any second instance in the same post / page will be ignored upon frontend rendering and not show up.
<h4>TIP</h4>

Banner alerts are custom alerts to notify your website visitors of promotions, alerts, events, etc. These display at the top of the website until they are dismissed by the visitor. Any new visitor who has not been to the website will see these until they are dismissed.
Banner alerts are configured just like a post or page with support for title, content, and excerpt. The plugin settings allow you to define which parts of the alert to display and whether or not to link to the full post. You can run more than one alert at a time and activate or deactivate as needed.
This plugin is ideal for:
<ul>
<li>Important operational changes</li>
<li>Technical notices</li>
<li>Time-sensitive appeals for donation or action</li>
<li>Terms or agreement changes</li>
<li>Privacy notice acknowledgements</li>
<li>Service outages or maintenance messages</li>
<li>Special offers or promotions</li>
</ul>
