ok sure, everyone's donating money for poor/sick people now but during all this shopping, maybe we should donate a little time. i said this in one of the GP newsposts today, but i do think it might be a good idea:
Donate some time out of a weekend day to go down to a local game store (EB/Gamestop, even Wal-Mart or Target) and offer your ESRB knowledge to the parents looking for games.
maybe print out some ESRB flyers and hand them out.
i know sometimes while i'm just browsing in stores i get asked questions, or i'll overhear some confused parent or grandparent who is being tricked into buying inappropriate games so i interject. helping explain what is and is not age-appropriate and what kind of game genres there can be a good way to educate away the fearmongering.
and while you're at it, hit up the teen/adult gamers for the ECA!
