Hi Dave,
The page simply shows how to set the background of any part of your page to an image.
I am working on the next update and indeed there are some improvements to the signup form generator already made including surrounding the form in a basic HTML table, which lines things up the way you requested.
While I cannot instruct you on HTML basics, I can provide an example form for you to use:
<form method=post action=http://example.com/mail/signup.php>
<input type=hidden name=list value=1>
<table border=1 cellspacing=0 cellpadding=5>
<tr>
<td>Name</td>
<td><input type=text name=fname size=15></td>
</tr>
<tr>
<td>Email</td>
<td><input type=text name=email size=25></td>
</tr>
<tr>
<td colspan=2 align=center>
<input type=submit value=Subscribe>
</td>
</tr>
</table>
</form>
I highly recommend Googling the phrase "HTML tutorial" as this is pretty standard stuff.
Regards
