Hi Shaharuddin S., I noticed your profile and would like to offer you my project.
Would like to create an app similar to Wikipedia, using an open source Wiki software called Dokuwiki, to be used as our Corporate Knowledge base (for internal staff references). The reason why Dokuwiki was selected is its ability to search for keywords on text content and in uploaded pdf files, It comes with access controls and plug ins / extensions. The app should be mobile phone and tablet friendly.
We can discuss any details over chat.
