how do I take my posting off this site once my tickets are sold???

:huh

The best way is the change the subject line to “SOLD” and one of the moderators will remove it for you.
Just post a reply to your original post and change the subject line.
That way you won’t be getting any more responses. :flower

If you go to the board that you posted in, say, tickets, find your original topic on the subject list. On the far right of the row, there is a little trashcan and a lock. Click on the trashcan to delete the topic. No one else can do it bbesides the person who started the topic or an administrator.
Same for locking the topic, but just use the lock icon instead. No need to wait for administrators to clean up the board.
