Ignore default text in jquery validation plugin

JavaScript
1

Hi,

I am using the jquery validation plugin (bassistance.de/jquery-plugins/jquery-plugin-validation/id) for a bit of client-side form validation. The plugin is working great but I cannot figure out how to force it to ignore some default text within a textarea. I would like the default text to still be considered invalid.

<form action="#" id="landingForm">
<p>
<textarea id="askTexarea" class="required textarea" name="askTextarea" cols="7" rows="3">THIS IS THE DEFAULT TEXT</textarea>
</p>
<p>
<label for="askExpert">Pick an Expert:</label>
<select id="askExpert" class="required select" name="askExpert">
    <option></option>
    <option>CHOICE 1</option>
    <option>CHOICE 2</option>
    <option>CHOICE 3</option>
</select>
</p>
<p class="email">
<label for="askEmail">Enter your email address:</label>
<input id="askEmail" class="required email" name="email" />
</p>
<p class="submit">
<input class="submit" type="submit" value="Ask a Question" />
</p>
</form>

You will notice in the first textarea there is default text. Does anyone know how to make the validation plugin ignore this text and consider it invalid if a user submits the form with this default text or if the textarea is empty?

Thanks in advance for you help!
