Comment 12 for bug 35728

Based on comments in bug #2879, I found https://launchpad.net/projects/emacs/+edit but it says "Not allowed here. Sorry, you don't have permission to access this page". What permissions do I need in order to be able to do this? Is this documented somewhere? Should I submit a bug report against Launchpad to get an administrator to add the link from the project to the bug tracker?
