If anyones still using this on v3.0x and your having trouble with smilies I am sure theres a typo in this line
PHP Code:
if ($botqusetandsmilie == "1") {
which should be
PHP Code:
if ($botuserandsmilie == "1") {
Status on the 3.5 functinality I have got to is now, ACP option appears and seems to function and smilies are by the looks spot on, and I seem to have managed a little extra, but I am not going to say anything on that till further testing.
