"It's things like that, all kind-of strung together, that really build up," she said.

This is the first Queer Harvard Month, Aceituno said. In the past, the BGLTSA has sponsored a BGLAD week with tabling at the houses, a dance and a number of discussions. The acronym stands for Gay and Lesbian Awareness Day.

There are 23 events planned for Queer Harvard Month, and most have been successful, Aceituno said.

"It's been really good so far," she said. "We had about 150 people, tops, at the beginning of the conference at the IOP, and we've had 219 people turn in to our Web site so far. So we're reaching upwards of 300 people so far."

The success of Queer Harvard Month has been tempered by the graffiti in Dunster House and the poster disappearance, Aceituno said.

"The message is that there are homophobes at this school who will do what they feel is necessary to fight us. But we're not going to be passive, we're not going to let them walk all over us," she said. "A group of us got together to re-poster tonight, and we'll see what's still there in the morning."

Aceituno said that she does not have any suggestions for measures that might prevent future poster disappearances.

"We did have a few people say they were willing to hide out in the bushes and jump out on anyone who tries to take down the posters," she added
