No Packagist, ao clicar em "Submit" para incluir o repositório https://github.com/edhoe/erh-buscador-cursos-alura, exibe a mensagem:
Warning: The vendor name "composer" was already claimed by someone else on Packagist.org. You may ask them to add your package and give you maintainership access. If they add you as a maintainer on any package in that vendor namespace, you will then be able to add new packages in that namespace. The packages already in that vendor namespace can be found at composer.If those packages belong to you but were submitted by someone else, you can contact us to resolve the issue.
E não permite fazer incluir o repositório no Packagist
Já fiz esta operação diversas vezes, alterando o nome do repositório no Github para que não tenha a palavra "composer", mas sempre exibe esta mesma mensagem, que me impede de efetivar a inclusão do repositório.
