If your room redec request was denied, just ask us about it. If there's no one answering your xhelp, ask again later when one of us lovely admin people is on the @who list not idled.
USUALLY room redec requests would be denied for one of three reasons:
1) It is not fitting with the theme of the MOO, or the area of the MOO in which it exists (i.e. being from the wrong time period, or too clean)
2) It is too riddled with spelling errors or typos to be a set description =P Run it through a spell check if you think this may be your problem.
3) It would clearly cost a ridiculous amount of money to do it (though I suppose this would be negotiable and debatable)
Check your room redec request to see if any of these things may apply, try correcting them, and resubmitting. If it's really none of the above, hound us until we tell you what the hell is wrong with it, baby!
