Would it be possible to change the "default" text in the comment boxes on a wiki? I'm talking about the grey text that is present in a text box when nothing is typed in it; for example, when a new forum post is made, the top box says "What do you want to talk about?"

Another example on the Steven Universe wiki:



The message I specifically want to want to add is something along the lines of "Please remember to be respectful when posting a comment, and think about if your comment is actually necessary or not before posting." (It needs some rewording but you should get the idea.)

I've had some comment spam trouble on a wiki I'm an admin on, and I want to try to find a solution besides blocking the offenders.
