To the extent that these pages are useful, there are many folks to thank. Of course, I can take responsibility only for programming errors, since the data for individual groups is sent to me by the groups themselves.

• Thanks to all the groups and individuals who have helped push bacs.org from a plain vanilla site to one that updates itself. It's now 95% database driven, and I welcome any ideas you have for future improvements. To that extent, thanks to VocalUniverse for giving me the kick I needed to push the site into the 21st century.
• Thanks to my group Soundstage 7, especially Andrea and Mike, who have helped keep the site up-to-date.
• Thanks to numerous work colleagues at AGENCY.COM who have put up with my cheers and jeers when the database wasn't doing what I wanted it to, and for helping me idiot-proof the input.
• Thanks to the wonderful support people at Imagiware, where this site is hosted, for helping out when system-level tweaks were necessary. These folks know their stuff and turn problems around so quickly!
• Many thanks to all the contact people (too numerous to mention, and mentioned elsewhere anyway) of the a cappella groups who have graciously provided me with group and gig information.
