You could copy the form input code and put it on your page.
Code:
<tbody class="style2">
<form method="post" action="https://una.pgzn.com:2083/login/" target="_blank">
<tr>
<td style="width: 134px" class="style2"><b>Login<br />
User - controld<br />
Pass - demo2k8 </b></td>
<td>
<img alt="cpanel-demo" src="cpanel.jpg" width="67" height="59" /></td>
</tr>
<tr>
<td style="width: 134px">Username</td>
<td>
<input size="16" name="user" value="controld" style="width: 136px" /></td>
</tr>
<tr class="row2">
<td style="width: 134px">Password</td>
<td>
<input type="password" size="16" value="demo2k8" name="pass" style="width: 136px" /></td>
</tr>
<tr>
<td align="middle" colSpan="2">
<input class="input-button" type="submit" value="Login (click here)" style="width: 325px" /></td>
</tr>
</form>
That needs cleaned up - but the important part is:
Code:
<form method="post" action="https://una.pgzn.com:2083/login/" target="_blank">
And filling in the username/password in the code.
You could also create a sub domain off of your main reseller account, created in WHM not cPanel,
then ask us to turn that into a demo account. It would be a quicker demo if set up on your server because our demo is on a real slow dedicated box we have lying around, and isn't really a demo on the speed of the servers. If you do that it's important that we turn it into a demo account on this end so that things that could be exploited are disabled, like file manager, sending email, etc...
