How to use it for academic purposes.
How to use it for account management and responsible use.
There are many topics other than "don't tuch that strangers weewee in da park" that most PSA focus on entirely. After all, the Internet is basically turning over an entire new age. Instead of driving children away from it, we should encourage its safe use, instead of listing everything bad about it (theft, 4-chan, perverts, Encyclopedia Dramatica, 4-chan...)
I do despise Internet PSAs, though.
