But The Observer has learned that there's no space left in the Real Estate Board of New York class that's being taught next Monday by the ladies, plus Clark Halstead (who started his own eponymous brokerage after co-founding Sotheby's International Realty).

If you're an ambitious agent, show up at REBNY's Lexington Avenue headquarters at 5:30, and push your way in. Ms. Corcoran (whose first book is called If You Don't Have Big Breasts, Put Ribbons in Your Pigtails & Other Lessons I Learned from My Mom) might give some hints about her new work. And Ms. Sunshine, according to a publicist, will be talking about "how she transformed new condominium development into an upscale lifestyle approach." Sounds awesome.
