Hello there :) I just merged all my CSV files from all my different emails into one big file. I managed to import it in TB, playing with the checkbox for the matching fields so far so good but some of my contact have 3 emails, and i need those. so i added a custom field in TB, for the 3rd email (cause the default in TB is 2 emails) then, if i edit a contact, add a 3rd email to it, it all display ok in TB the issue i have now, is if i export my adress book back to CSV, that 3rd email information is lost during the process. the "custom" field in the csv field is blank, and the "3rd email" i created in TB is nowhere to be found anyone could tell me if it's a TB limitation, or if i'm doing something wrong? :) many thanks, Baptiste
