It s not really an abbreviation in the sense you mean it s two words combined to make a new name In that sense it just becomes a proper noun The thing with forex is that it actually refers to foreign exchange and is thus an abbreviation whereas Pasmo is simply the name of something and the etymology is not crucial to its function as such And even if you insist that it s an abbreviation there s still no reason for it to appear in all caps The forex page on Wikipedia doesn t even use all caps for forex so that kind of dumps your argument not to be rude but this is the case Also note that EBay when refering to itself on its website and in reports etc starts sentences with eBay but the Wall Street Journal quite rightly follows convention and begins such sentences with EBay I find the trend of using all caps when there is no basis for doing so highly annoying It also quite simply goes against well established rules of style Regardless of what style the company forces its English translators and copywriters to follow probably against their will for the corporate website and materials Wikipedia is free to follow normal English conventions Wikipedia does not have to support the company s misguided use of SHOUTING which is and this is an unverifiable statement based on experience probably due to a lack of understanding of English style conventions or a refusal to accept them even after they have been explained rather than due to an informed decision based on whether the name constitutes an acronym abbreviation or not The name should appear as Pasmo
