Thanks UK
Here is the button I am working with in the newreply template:
<input type="submit" class="button" name="sbutton" id="{$editorid}_save" value="$vbphrase[submit_reply]" accesskey="s" tabindex="1" />
Right now when a user hits it to post a reply, they get the $vbphrase"postthanks_moderate" in a splash screen and then the user is automatically redirected back to the thread.
I need them redirected back to the index instead of the thread after they submit thier post, and I can't seem to figure this out
