You can't just delete sets. (Only Admin can do that). You have to submit an IR on the set you want deleted and the process begins there. If there are no cards in anyone's collection it's as easy as chosing the delete checklist option and waiting until two other level 8s approve it (usually a couple hours at most) but if people have them in collections that's harder and I don't fully understand the process.
It's best, when sending an ir, to be as detailed as possible. For instance if a set is listed twice, drop a link to the older or more correct listing in the IR.
VERY slow trading due to health problems. Not transferrable so safe to trade with, just moving is painful and can't always access the cards.
