I just checked the statistics quickly for the campus.dokeos.com portal. We've cleaned up the portal completely on the 12th of October, and yet... we have already reached 1400 courses and 13000 users.
campus.dokeos.com is provided as a free service to host courses inside Dokeos, but without any implied guarantee, so we strongly recommend you keep a backup (you can do that in your course options) at least once a month.
