Yes, I understood your post in the general sense. But how can I access the codes for all six reactions? Are they listed somewhere for me to copy? I only have one install right now.

I see you were saying to update using the MySQL commands. But I'm not sure where to start with that. I will paste the code that is currently in there in Studio for thumbs up. Does this look right (except for the question mark, obviously)?
