Although this rule is more specific to the chat rooms rather than the forums.
4. English, please.
Please speak mostly English in the chat rooms so that others can understand you. At least please do not dominate the voice/video chat (or text chat) with conversation in another language.
Over the years we really haven't had much traffic from persons who only speak Spanish so I really don't see a specific forum being created for it. Years back we actually had a Spanish room in chat and it was almost never used for that purpose because of the lack of Spanish speakers.
I know over the years we've had a number of users who were not English fluent that successfully utilized Google translate for the purpose of reading and posting (it just takes a bit longer).
I wouldn't gripe if someone were to join and post an occasional thread in Spanish any more than I have griped about some users occasionally posting in Norwegian, Swedish, German, etc.
