Ma injini amagawana - mndandanda wazolemba zomwezo, ogwira ntchito omwewo, zoletsa zomwezo. Zomwe Word zimawonjezera ndi zomwe zimawoneka kuti zimasiya mtundu wa Office ndi zomwe sizimachita, zomwe ndi mafunso omwe amafunsira ntchito iliyonse. Amayambanso kuchokera ku chinthu chimodzi cha mtundu womwe umatchedwa izi: fayilo ndi zip ya XML, kotero kusintha kwa malemba ndi ochepa ndipo kunenepa kwambiri ndi pafupifupi nthawi zonse zithunzi zophatikizidwa.
Kodi ndiyenera kukhala ndi akaunti, ndipo kodi zinthu zina zimasunga?
