Forgive me I missed some original posts on not using 'brand' names on LACTNET. I thought that was not permitted from the beginning. I wondered why from the beginning, but didn't think to ask. I subscribe to 6 other lists - 4 of them medical. The professionals on those lists always discuss their instruments and machines with the complete name. I wonder why we can't do that here? If this question has been answered, please ignore me! I can plow through the digests for the answer. Sharon Terry Boston area, MA
