What about Compuserve?

 Compuserve can still be said to be the central communcation spot
 of the CA-Clipper developers' community.  14400bps access costs at
 least $4.00 per hour in the United States and Canada, and much
 more elsewhere.  When you join Compuserve, type GO CLIPPER to
 join the Forum, where Computer Associates staff people and (I mean this
 very literally) hundreds of other CA-Clipper developers visit every
 day to check messages, ask questions, and offer help.  The CLIPPER
 forum also carries what must be the largest collection of public
 domain, shareware, and freeware of interest to CA-Clipper
 developers.

 For more information on joining Compuserve, please call (in the
 United States) 1-800-848-8980.  This is a voice-only number.
 I will be happy to provide phone numbers or other pointers for
 non-U.S. users.
