Returns the send button, if all requirements are matched
This is only useful within the lb:area_makecomment tag.
<input type="submit" name="commentsubmit" class="commentsubmit" value="send comment" />
This submit button only shows, if the user did at least one preview before (This is for fighting comment spam). Plus the user has to write at least one character into the “message” field OR uploaded a valid audio file.
