Each one of Expat-blog's forums has 5 separate "language-specific" versions. There are forums for English, French, Spanish, Italian and Portuguese postings. In each of these forums members should be posting only in the language of that forum. If you are in an Anglophone forum, then in consideration for all of the other members please post in English only. Similarly if you are in a Francophone forum, then you should only be posting in French, etc.
You can access any of our 5 language-specific forums by clicking on the flag icon that you see in the green banner at the top of each page and selecting the desired language in the drop-down window.
Oh, and if the title fooled you and you were thinking that I was talking about profanity... well watch your language too, that's a no-no here, OK.
