How to add manually a conference poster co-author to the publication page if that co-author is not at RG? The problem I have with this is that it seems to be impossible to add someone who is not listed as a previous co-author or collaborator. When creating a publication page for a conference poster, it is possible to select only the authors who appear in an automatic list, but not to enter their names manually. A request to change the author list in the existing publication page also does not work (the request is rejected). Maybe someone knows what to do in such a situation?
