Improving Emacs package descriptions on melpa, elpa, and marmalade repositories

Question

The Emacs package descriptions are sometimes not very descriptive or have typos. How can users improve this?

Is there a bugtracker, or an public repository like GitHub for contributions?

You should not use M-x report-emacs-bug, because the repositories are not part of the Emacs code itself.

Answer 1

The development of marmalade takes place on GitHub. All bugs and requests concerning marmalade should be sent as issue to the marmalade repository

I have found a contact for elpa here: http://tromey.com/elpa/upload.html

I found no bug tracker the other repositories yet.
