Category talk:Street signs in Warsaw (City Information System)

I do not understand the idea of this category so far

What does that mean: zgodne ze standardem MSI - I guess it is an abbreviation for Miejskie System Informaczyjne or similiar ? Does it mean, that this category covers only the new type of street signs in Warsaw ? Old ones should be in the basic Category:Street signs in Warsaw ?? I do not think, that the title of this cat is very practical (specially for non-Polish-speakers). Those are just modern street signs, street signs always are poart of a city information system. Maybe better to call it Category:Street signs in Warsaw (from 1996). --Wistula (talk) 10:34, 9 July 2011 (UTC)
