I bought this program several months ago but other than look at the sample file and read the manual and organize my files, until last night I hadn't used it. I imported my 982 names from Legacy 3.0 with no problems in about 3 minutes, what a relief. I have User ID#'s for all my people in Legacy. They are A-0001,B-0001 etc. I would like to use these numbers in Clooz as well. I was starting to enter these User ID#'s into the Alt.ID spot in Clooz but on reading the manual again, I find that this column seems to be reserved for future imports, something I will definitely be doing. I'm a little confused about lower RIN#'s at the moment, and don't need to add the additional imports now. Could someone please tell me where I should be adding my USER ID#'s. Thanks, Elsie
