Вікіпедія:Userboxes
Вызир
англ.A userbox (commonly abbreviated as UBX) is a small colored box (see examples to the right) designed to appear only on a Wikipedian's user page as a communicative notice about the user, in order to directly or indirectly help Wikipedians collaborate more effectively on articles.
The first userboxes were introduced to support the Babel inter-language effort by indicating users' skills in other languages.
