After looking around in various LISTS databases (LSTSRV-M, LSTSRV-L, and UDD-L) I still know very little about the listserv'er UDD functions. 1) What really is UDD (user directory database)? 2) Why do only 7 sites supports use this feature but the udd-l list has 137 members with little or no activity? 3) Where are the LISTUDD and LISTUDDA memo's? 4) Has this function been replaced with other types of phonebooks (IE CSO, x.500, gopher, cwis, finger, whois) 5) Is the UDD function a netwide (BitNet) database? 6) What does the MASSUPDATE function do? I was digging around in the listserv memo's and doc's and became very curious about UDD. I would appreciate any information about UDD in order to quench my thirst. 7) does curiosity ever kill the cat? Thanks in advance. :-) Respectfully Yours, George R.
