Aha, I do not have access to the repository. I'm not sure why they decided to keep server files with client files, it doesn't make sense to me either.
Either way, listing all addon groups as an available modset for any server under online would solve any problems with contents of repository not matching what you want to use. For example, the repository for our addon server does not contain the soundmods or the ares mod, however we are allowed to use them (the bikeys are on the servers), and so I could not use the repository under modset for our server anyway, I would have to use my custom addon groups.
