Embeddable Song Request Form for Radio Stations
Designed for Radio Stations
PlayMe was requested by a radio station deejay and built to best serve both the studio and the listeners.
<ul>
<li>Listeners may provide their name, the artist/song name, and a dedication (or comments), to make realtime requests to Radio Stations and Deejays.</li>
<li>The form is easily embeddable using the shortcode [playme] and can optionally require Google’s reCAPTCHA to verify requests before they’re submitted. Put “[playme]” on its own line in the page content (using Text View) to position the PlayMe form where you want it to appear on your page.</li>
<li>On the backend, requests are shown in a list that refreshes passively every minute, and can be dismissed/hidden once the request has been addressed.</li>
<li>For privacy, the only information captured (apart from what’s entered in the submission form) is an IP Address, to offer some insight to site owners about those who are submitting song requests. </li>
</ul>
