This page captures some of the issues that may be encountered in uploading my GEDCOM from Cumberland Family Tree.
According to the WeRelate Help:Naming conventions page the GEDCOM's Firstname field and the entire contents of the GEDCOM's Lastname field are used to create the Page Title. GEDCOM's exported by Cumberland Family Tree have only a GEDCOM Name field.
Surnames are currently all stored as all uppercase characters in Cumberland Family Tree. WeRelate seems to want mixed case surnames.
