With VideoLAN, we're not on github, but I believe we fit the 'large open source project' description. We host VLC, FFmpeg, x264 and quite a few related libraries. For VLC and all related VideoLAN projects, we're moving to our own instance of GitLab hosted on our infrastructure. And to be honest, it's quite good, but a few stuffs are ridiculously limited, to the point that some people in the community are resisting th…
1. Our EE version has the function share project with other groups http://doc.gitlab.com/ee/workflow/share_projects_with_other_... If this is essential for you we'll give you a free lifetime license for GitLab EE.
2. You can add custom labels on issues and the searches can be stored in urls that you can bookmark and use in links. You might have considered this already and need more functionality. Maybe it is best to discuss this in an issue so I created https://gitlab.com/gitlab-org/gitlab-ce/issues/10712 Please add there what you need in addition to the labels functionality. We addressed the long list of items raised in the original Google Doc letter below the signatures in https://gitlab.com/gitlab-org/gitlab-ce/issues/8938#improvem... The first item under improvements details our reponse to that question.
3. In GitLab you can give each user a fixed number of new projects. That should prevent people from storing a excessive amount of repo's. But feel free to make a feature request to limit people to only forks. As other replies have indicated that still allows people to work around it but at least the intention will be clear.
4. A custom landing page and logo is an EE feature http://doc.gitlab.com/ee/customization/branded_login_page.ht... We think this is more relevant for larger organizations so we're comfortable for having it as EE only at the moment. As mentioned under 1. we're open to offering you (and other open source projects considering self-hosting) a lifetime EE license.
I'll be in the comments today (just woke up in SF). You and any other open source project can always reach me at sytse@ company domain to get assistance or claim the EE license.
