Somewhat relatedly, the forum terms of use addendum currently does not mention the ForumMagnum software, which is GPL-v3. CEA itself might have obligations under the GPL to other contributors to the forum software (i.e. anyone who contributed to it and was not a CEA employee), like informing forum users of the terms and conditions of the GPL and not imposing further restrictions on them. I suggest looking into this to see if the EA Forum terms of service need to be modified in order to comply with the GPL. [edit: reworded to avoid being interpreted as legal advice]
