Do I need to send jid, name, ask, subscribe, and all groups every time I want to change the rosteritem? Is there a way to simply signify that only x attribute needs to be changed, or are attributes ONLY changed when they are included in the body of the roster request. Meaning: if there is group info, only change that, if there is name info, only change that, etc? Matt Diez </BODY> </HTML>
