Now there's really something to talk about. "Dance in the District" -- a forum at 6:30 p.m. tomorrow at George Washington University's Marvin Center Theatre -- comes at the right time, with the relocation of the Dance Place from Adams-Morgan to a new, larger home in Northeast Washington and a new spirit of unity in the dance community. Participants will get a chance to hear choreographers, dance managers and space designers such as Melvin Deal, Carol Foster, Liz Lerman, Mike Malone, Myrna Torres, Bill Warrell, Maida Withers and Wendy Woodson talk about dance management problems and solutions.

Chief among those problems is finding performance spaces. "Even if we produce every weekend, we still can't meet the demands of the entire dance community," says Dance Place Executive Director Susan Cushing, who will attend the forum.

Another topic of discussion will be displacement of cultural groups -- a situation with which Cushing is quite familiar. "Our feeling is that we helped develop Adams-Morgan, and once Adams-Morgan was developed, they got us out because they could then demand higher prices for property. We were lucky enough to be able to purchase, but for smaller arts organizations that's just not an option," she said.

The forum is sponsored by the D.C. Commission on the Arts and Humanities. For more information call 724-5613. A Chorus of Thanks

A select group of choruses across the country were undoubtedly singing the praises of the National Endowment for the Arts when Thanksgiving rolled around, and Washington area choruses were among them. Of $443,000 in music program grants announced over the holiday weekend, local groups received $24,900.

"We were the first chorus that ever got a grant when they first started," said Norman Scribner, director of the Choral Arts Society, which received $5,000. "We continue to be grateful for all the grants in the intervening years." Choral Arts also is celebrating a birthday: Twenty years ago this month the group gave its first performance -- the "Messiah" with the National Symphony Orchestra at the symphony's former home, Constitution Hall.

Other groups receiving funds: Paul Hill Chorale/The Washington Singers, $10,500; Musikanten, $1,500; Oratorio Society of Washington, $3,400; and Washington Bach Consort, $4,500. Naturalist Center Draw-In

The National Museum of Natural History's Naturalist Center hosted another Draw-In yesterday, the 50th since it began the every-other-month affairs in 1977. Professional science illustrators are on hand to answer questions and guide participants in their attempts to artfully reproduce fossils, insects, plants and shells. Naturalist Center director Richard Eltham estimates that the ages of the participants range "from 12 to 72," but most, he says, are high school kids or of college age.
