Hahlo 4 Beta Exactly two years ago today I announced the beta of the original Hahlo and now after a long, long, long wait I’m happy to announce I’ll be opening up the Hahlo4 beta later this week, all you need to do is head over here and plug your username into the super simple signup form, then make sure you are following hahlo on twitter so I can send you your super secret beta password. Easy as that.
