Oblak Tagova - Svi jezici

While this is just fine, if you wanna go Croatian all the way you can also use "Oblak ključnih riječi" but I'm not the one for forceful Croatization :)

PS, we don't use the term "cloud" simply: tags

Still not sure what it means. Wrote clouds in the diminutive since the words for "cloud" have negative connotations when used like this.

In Wikipedia Tags-Cloud was translated to german by "Wortwolke" for informatic use
