Dear All, Thanks for all of your answer, but that's what I wanna know is about maximum number list that can be handled by listserv. I ask this, cause I still develop our list system based on listserv technology that will operate in more than 250K members ( our purpose is to create list-system for over than 1,000,000 members ) and every member have capability to create a list by himself. And I wonder if the listserv archiving capability have "this" limitation, maybe I will not open the archive capability to public, is it right ??? FYI, We have developed "hashing technique" to expand capability of archiving file, but we still can't expand for maximum number of list that can have archive ..... regards, - erry_r - ----- Original Message ----- From: <[log in to unmask]> To: <[log in to unmask]> Sent: Tuesday, March 27, 2001 9:49 PM Subject: Re: Limitation on Archiving list
