Hm, well if that really is the case then this rule will come into play..
RULE: Chops can go for a maximum of 5 days (120 hours) without being answered, however after this time has passed anyone may post another chop. (check the date and time of the chop's posting)
So wait another 3 days and if nobody has answered it (or HTID hasn't replied to the answers) then anyone may post a new chop. Please refer to the time of the posting as well (and make sure your timezone settings are correct in your profile)
