Censoring kids computer use in libraries

There's an interesting conversation happening on the library_grrls LiveJournal community about what to do about young girls using library computers to bully others via e-mail. Someone asked what others would recommend and there are some interesting ideas about censorship and how much to censor, etc. It's a bit dry part way down, but I encourage you to read all the way through. The last poster (as of two minutes ago) made some very good points about how if it's not something we would stop adults doing, then we shouldn't stop kids from doing it because we're not their parents.
