"Are you ready for Philadelphia to be the biggest town in America without an alternative rock station?"

That's the question being asked at Y100Rocks.com, a Web site formed to protest the imminent format change by Radio One at Modern Rock outlet WPLY (Y100)/Philadelphia.

The site lays out what happened to Y100: "On Thursday, February 24, 2005, 100.3fm, WPLY, Y100, was taken off the air. After nearly 12 years at 100.3, Alternative Rock disappeared from the Philadelphia radio landscape. With it went the musical companion of over 500,000 residents of the Delaware Valley. Y100Rocks.com is being put together to give the fans and staff of Y100 a place to come to share, to vent, and to work together towards the future."

Y100Rocks.com also urges fans of the station to "protest the loss of Y100 and send a message to the owners of Radio One to demand that they return Y100 to 100.3fm immediately. Only if we complain loudly enough will we be heard!" The site gives out the e-mail addresses of Radio One CEO Alfred Liggins and COO Mary Catherine Sneed.

In the meantime, they have set up an online radio station and given it to the Y100 staff, with some staff members broadcasting from the Internet station. E-mail accounts for all the former Y100 staffers have also been set up.

Y100Rocks.com also points out, "In the time since Y100 signed on in 1993, the station has hosted more than 150 Sonic Sessions, held 8 FEZtivals and 8 FEASTivals, raised over 400 tons of food and donated more than $400,000 to charity via the Camp Out For Hunger and Sonic Session releases, supported local bands, played more than 1,250,000 songs (and just a few less commercials), and rocked Philadelphia 24/7/365 with more wit, humor, intelligence, and fun than any other station on the dial. And more importantly, it's been the musical hangout, home, and club for us - over 500,000 Philadelphians."
