We welcome all additions and corrections to current entries in the database. However our capacity to carry out such improvements is limited at present, since as a ‘portal’ we are only able to make changes in the Portal’s life summary page with biographical information. Proposed changes will only be carried out if they are accompanied by corroborative references to reliable sources. We kindly ask respondents for their patience, because our operational capacity for dealing with such additions and corrections is as yet limited.
