	You can also edit the <a href="b2template.php?file=b2comments.php">comments' template</a> or the <a href="b2template.php?file=b2commentspopup.php">popup comments' template</a>, or edit any other file (provided it's writable by the server, e.g. CHMOD 766).<br />
	<br />
	To edit a file, type its name here:
	<form name="file" action="b2template.php" method="get">
	<input type="text" name="file" />
	<input type="submit" name="submit"  class="search" value="go" />
	</form>
	<br />
	Note: of course, you can also edit the files/templates in your text editor and upload them. This online editor is only meant to be used when you don't have access to a text editor...
