When you are working with Plone Add-on products the best practice is to upload your releases to PyPI and Plone.org.
Since all Plone packages are based on Setuptools, you can create two aliases to make commands shorter :
$ python setup.py alias plone_release mregister sdist mupload -r plone.org
$ python setup.py alias pypi_release mregister sdist mupload
Setuptools will create in setup.cfg two aliases, and you will be able to register and upload your package with plone_release and pypi_release, wich is shorter;
$ python setup.py plone_release
$ python setup.py pypi_release
