As per the market rules you are allowed one type of open post per every 3 pages and may only make a new one of the same type when the original has reached the third page and has been locked. I.e you may have one open buying topic and one open art commission topic in the same forum, but not two of the same type.

As you still have one open on the 2nd page of the art market I’m going to go ahead and lock this one. Please use the one on the second page of the art market instead, thank you.
