Chasing each other 

I guess you're doing the same thing as me - working through the Category:Pages with missing references list to correct them.

I don't want to bitch, but it does seem that on more than one occasion you've been too hasty, and committed without checking results.  For instance The Grapes of Wrath (film) - it quite clearly states at the end what the problem was (needed a ) but all you did was insert another  immediately before the one that was there, which didn't cure anything. 

I take this exercise as an opportunity to apply other edits to the article too, if it grabs my fancy.  So in this example (The Grapes of Wrath (film)) the simple solution would be just to do what the error message tells you.  But the longer solution, and probably what the original author wanted, is to remove the group name from the .

I'm also keen on articles having proper citations, which aren't dead, so I often try to clean the citations too.  That usually involves a change from a straight  style to a full-blown  because then I can add a date showing when the link was last checked.  Takes time.

Like I said, I'm not really bitching, but if you don't do it right, then you're wasting your time.    mytime= Thu 11:19, wikitime=
