Hello, I want to modify Livelink in such way that when any user (except Admin) want so change permissions or whatever that involves listing Users I want that only displays the Users that have the same group.For example if user A,B,C,D are in X group and G,H,I are in Y group, I want that when the user A lists the users and gtroups only display A,B,C,D and not G,H,I.Any ideas?, where can I start, does anybody have done something like this.?Thank youCarlos del Castillocastillo@auracom.com.mx
