I'm sorry, but I can't access the manual
You passed the exam to enter the forums as a member, yet you can't remember about not double posting, nor about keeping your question running in the same thread. dont start a new thread to continue discussing your related thread. For instance, I just answered you about how to change the room. if you then go on to ask, "why is this code that I just used not working for chaning the room", you would continue to ask in the same thread.
same thing with criticizing an art piece. we dont start a new thread if we posted one before, updated the image, and are uploading the newly done piece.
