    RE: FW: FW: iSCSI: support value of ?



    Julian:
    
    I first brought up the subject of eliminating ? last December.
    Your reply is attached below.
    Perhaps this latest round of e-mail postings is enough to
    support my contention that ? should be eliminated??
    Thanks,
    Bob Russell
