One area you may wish to expand is EMOTICONS. The basics are available here but more nuance of expression would enhance communication, and make ET a lot more fun too. All PLUS and no downside as far as I can see. Won't take any more bandwidth to speak of ... exchange of INFO is at least half the reason for success of ET, and I submit that "entertainment in posting" is the other half. Custom emoticons provide more of both, communication and entertainment, can be unique to your site and welcome addition here.
