The verb seems to be at the infinitive mode, and as you know we do not accept requests without a conjugated verb, except when infinitive is used as an imperative form or another one I wouldn't know according to my poor knowledge of Bulgarian?
Thanks ViaL!
In French I had "Avoir un beau sourire", infinitive. In English I got "Have a nice smile"-imperative-. Just comparing the two let you be in doubt about ATT efficiency!
