Despite rumours being spread, the GENi Conventions are not different to any 'South African Genealogical Standard'. If such a standard existed they would surely recommend that you use the fields as they are labelled in the software you are using, as well as recommending that you follow the published Conventions, so that you work "for the good of all" in that particular online environment. Creating 'work-arounds' that suit private interests would not be encouraged.
