    Fill Mail Addresses: Manual entry of addresses to database, export

    * Note: SF gives wrong "latest version" info (0.0.15 while it is now 2015 v. 0.2.0 - so select from Browse All Files). Manage the e-mail addresses you need for a mailing: input e-mail address, company, contact, etc and store in your (local) MySQL database. The input of the e-mail has some minor format-control and auto-complete which saves time typing. Make a selection to do a CSV-export to external online mailinghost. Keep the control over your addresses that are basicly stored on your own storage and not dependent from some provider. Keep metadata for yourself: entry date, collected by, source, intrest/productgroup instead of leaving them "in the cloud" for misuse by others. Platform: Gambas2 on Linux desktop.
