creating a page where teachers can register his fav language to teach as well as the other language he is able to teach

[ChristopherWong274]

Yes, we could include a system like when a volunteer teacher registers himself to the system. He can include the language for which it is easier for him to teach but also the subsidiary languages in which he is also able to teach. Then when a student search for a specific course in a certain language, the system will be able to match him/her to the perfect available teacher
