Dear Moderator ... First of all thanks and cheers for your moderating MolBio Archive. I got so much fun and help from this FTP host. And now I really want to upload my own program for Molecular Biology. I have written small editor using internal speaker Feedback Echo for user's typing and it might be useful for laboratory on DNA sequencing projects , I believe. Although there are so many Echo Editor for Sequence Input on Mac , I think no public domain IBM-PC version is available now ... I hope you accept my upload and archive it in your great FTP house . Thanks for reading me and in advance. Sincerely Rhee Hwan-Seok Dept. Mol.Biol Seoul National Univ. Seoul KOREA e-mail : hyunerho@krsnucc1.BITNET
