total no of translators for gnome?

["G Karunakar" <indlinux gmail com>]

Hi,
 In a presentation I have to make later this month..on opensource way
of translations..I wanted a rough estimate on how many translators
does GNOME  have across all languages.. is there any statistic on
that? or can it be calculated in some way (apart from asking each
language team)?
