I just upgraded my JoomlaComment from beta1 to RC1. You guys are doing a great job and thank you for providing this powerful commenting system for free.

I just noticed one bug in the notify email code.
in the file location below

comment/joscomment/templates/modern/index.html 

for the user email notification you have something like this..

<select name='tnotify' id='tnotify' class='inputbox' tabindex="3">{notifyselect}</select>

Now when you actually disable the user notification, it gives empty select box with no options. I think the code below should be fixed to include

<select name..............></select>

as well as the

<options></options>

in the comments.class.php
