I didn’t realize it was part of a plugin, you may still be able to edit the plugin if you can find the section with
<!– style=”clear: both;” class=”subscribe-to-comments”> –>
<input type=”checkbox” name=”subscribe” id=”subscribe” value=”subscribe” style=”width: 20px;” />
<label for=”subscribe”>Notify me of follow-up comments via e-mail</label>
just leave it <label=”subscribe”>
