[register_globals problem] My questions: a) is there any special reason it's being done this way in Wikipedia? b) any chance it can be changed? If yes, what can I do to help make this happen (I can write the code, test it and submit a patch)
No, and yes. You'll notice I already started doing that for SearchEngine.php. If you want to help me out with the others, go for it. Please see that as a model.
