You can sort the Compare List by the compare/merge/reject column or other columns also, like a spreadsheet, as well as by birth date etc. This may help you find people.
It is tedious to search through lots of compare reuslts, which is why it is recommended to use a small file with few people initially - walk before running.
Also if you potentially create more than ten duplicates, the import will be rejected (not approved).
I suggest you tick 'skip' for nearly all and see how the few remaining are imported.
Chris, having just been through that learning curve!
