After weeks of events aimed at drawing new members, Colonial Club and Quadrangle Club filled after the first round of the sign-in process, leaving only wait list spots available.
"Both clubs have really tried to do their best by having great events," Inter-Club Council President Corey Sanders '04 said.
Everyone who signed in to Quad received a spot, Sanders said, but "there were some people who signed in to Colonial who didn't get in."
"They all did fairly well," Sanders said, referring to the sign-in clubs. "No club did poorly this year."
The sign-in clubs have 378 new members this year, ICC Adviser Timothy Szostek '02 said.
"I think there were overall more people who signed in this year," Sanders said. The clubs "all were pretty successful in throwing some great parties . . . and keeping their members happy."
Though he cited several popular events, Sanders could not point to a specific reason that Quad and Colonial had such high interest.
"I never know what to expect," he said. "A lot of it just comes down to luck."
It is hard to predict what the sign-in results will be, but certain trends have emerged over the past few years.
This is the second consecutive year that Colonial filled in the first round. Sanders added, however, that they had to turn down more sophomores last year.
Quad has a different history. In 2001, they had only 35 new members, the smallest sign-in tally on the Street.
Over the past few years, Quad has worked hard to rebuild its image. And this year's sign-in results are a marked success for the club.

Exact numbers for the first round of sign-ins are unavailable because the Inter-Club Council voted to withhold numbers for the second year.
"It tends to be a stigma or a disadvantage for clubs whose numbers weren't as high as they would have liked," Sanders said.
He also said that there was "no real advantage" to reporting the sign-in results.
Sanders preferred to focus on the overall success of the sign-in numbers this year.
"We were happy about the total amount of people who did sign in," he said.
