There has been an interesting discussion about the pro's and con's of updating your school's entry on Wikipedia. Here is a cautionary tale from Dan Lovejoy:
"From someone who has been burned, then very stupidly drawn into that cesspool, I suggest staying as far away from Wikipedia as possible. Don't even revert vandalism - it will be used against you.
If you bother to read any of that, look at my Edit history, then compare it to what the "adversaries" claimed I did. It's terribly frustrating and I handled it completely wrong. (Note that I posted under my real name - I think everyone should, but it didn't work very well for me personally ;-)
Nevertheless - It doesn't matter if you are right - if all the facts are behind you - if you only edit provable facts or only remove vandalism and edit in your own name publicly. It doesn't matter if you know all the rules and the person with whom you disagree knows none of them. It doesn't even matter if you are willing to compromise. The person with the most time on their hands and the most lurid sounding accusations will "win" simply because they can keep going. And the formal complaint process is the most arcane, convoluted nightmare you could possibly imagine.
I don't believe Wikipedia is salvageable, but I believe its successor will be awesome! Let's hope for that."
