 Откако ќе додаде тема, ќе може да ја уреди, избрише или додели на некој студент, притоа студентот мора да стапил во контакт со менторот претходно на самата страна и да има договор помеѓу студентот и менторот за таа тема. Доколку темата е доделена, менторот може да ја одземе.

 Секој корисник може да ги види предлог темите на менторот на неговиот профил. Може да види наслов, опис, доколку се доделени или не. Ако е менторот, или пак студентот на кој е доделена темата, тогаш има посебно поле „Доделена на студент:“
