For eons people have complained that "Put the text of the new page here." is extremely unhelpful and promotes confusion among newbies to wiki; that it discourages people from doing anything further with the site as they don't know what they've stumbled into; and that it encourages a lot of useless blank, "Put the text of the new page here", and "What does this do? FJSDIOJDFS" pages. Longer, more informative messages have been suggested.

I like the new message, but it seems a bit more could be done. Why not modify the script so that it will respond with an error message if anyone attempts to submit a new article that contains the exact text of the "newarticletext" string? No matter what message you put in the edit box, there will still be newbies who misunderstand or ignore the message and create useless pages, but you can make it a little harder for them to do so.
