Put text in your comments box that disappears as soon as the viewer clicks in the box. Possibly useful :)
Default Classic 'comments.php' line 62
<p><textarea name="comment" id="comment" cols="100%" rows="10" tabindex="4"></textarea></p>
Although I have no idea of the vintage of my comments file, that line above now looks like this:
<p>
<textarea onFocus="this.value=''; this.onfocus=null;" return false; name="comment" id="comment" cols="60" rows="12" tabindex="4">
++++++++I have some text here++++++
</textarea>
</p>
Just something to play with really :)
