  • Did you know that Wordie is not available from all computers here in Buenos Aires? Last night when I tried to access the site, all I got was a perpetual "site not found" message. Earlier this evening, working from a different machine (I'm in an internet café), there was no problem. But this machine found the site, indicated it had potential adult content, and immediately closed down the window.

    The content filter has now been turned off. At least I think it has. If you are reading this message, we can assume that it has.

    Oh, you foul-mouthed Wordies, the porteños are onto you!!!
