I had a quick look and didn't see a way, but...is there the ability to delete or retract your own post? I wouldn't be surprised to see  it done just to cause a controversy. I too saw nothing wrong with the post. I don't necessarily agree with it, but it wasn't vulgar.
 They are, of course making it a big deal on the other site. I wouldn't be surprised if Agora deleted it. They are paid to do PR for ECU and MYER was bashing management. I think it should have been left here.
