March 23, 1999, San Mateo, Calif. - ONElist, Inc. (http://www.onelist.com), the leading provider of free e-mail list and group communication technologies for average users of the Internet, today announced that several major e-mail lists have recently switched to the ONElist service. The new additions demonstrate that ONElist is fast becoming the free list service of choice for owners of large e-mail communities and discussion groups.

Large e-mail lists (in excess of 10,000 members) have administrative and scalability requirements that often outstrip the capabilities of standard list servers. Managers of high-membership lists choose ONElist because of its best-in-class scaleable technology and superior services for hosting, managing and moderating large lists. Recent ONElist converts include ``The Closer,'' a 24,000 member daily baseball commentary and ``Ask Dr. Science,'' a 17,000 member list of fans of the popular Public Radio International (PRI) and BBC radio show.

``We built a highly scaleable and fault tolerant technology infrastructure to provide our users with a service they can always rely on,'' said Mark Fletcher, founder and CEO of ONElist. ``Although we support thousands of small e-mail list owners, ONElist is fast becoming the free e-mail list service of choice for owners of large e-mail communities who require a service that will grow with them and support their unique needs. We currently support lists in excess of 70,000 users, with more big lists switching to us every day.''

Founded in 1996, ``The Closer'' (thecloser@onelist.com) e-mail list is designed to foster discussion with people about baseball and develop community among its members. Thousands of registered fans receive daily commentary on baseball news and events, sharing their love of America's favorite pastime.

``Because I had over 24,000 users, I was looking for an e-mail list service that was robust and reliable enough to handle my fast growing baseball community. I also didn't want to fuss with the technology behind setting up a mail server or have to worry about it crashing on me,'' said Greg Shea, editor of ``The Closer.'' ``If you have ever experienced an unhappy baseball fan, you know why I needed a service that can deliver my daily e-mail commentary in minutes (rather than hours) and which isn't plagued by service interruptions. ONElist was the right service for my needs.''

The ``Ask Dr. Science'' ONElist e-mail list (drscience@onelist.com) is based on the popular ``Ask Dr. Science'' radio show broadcast worldwide each weekday on PRI and BBC network stations. ONElist helps ``Ask Dr. Science'' fans receive their daily dose of ``whizdum'' from America's foremost and funniest authority on the world around us.

``After looking at many different e-mail list services, I picked ONElist because it has the best features for big lists -- and because it is free,'' said Rick Alber, ``Ask Dr. Science'' Webmaster. ``Prior to ONElist, I employed a person to do nothing but handle bounced e-mails, a problem which plagues all big list owners. Now, ONElist handles this task automatically and at no cost. And the added bonus was it only took one day to transfer our huge list to ONElist, in spite of several tricky complications.''
