If you're having problems with the forum, you do not (and probably should not) go direclty to Sakura, as that gives her WAY too much to deal with.
If you'r ehaving problems in a specific forum, please try bringing it up with the moderator of that forum first, and if that moderator is giving you trouble try bringing it up with me or Kimiko first, as we're on considerably more than Sak is, and can handle things in a somewhat more timely fashion. In a worst case scenario, we will talk to Sak directly.
