Personally, I think you should find one based on what you like and in an alternative way. The official mentor program is closed, I think, but you can always get a mentor of some sort in another manner. If you're interested in a specific section, you can go there and start getting to know people and then if you become close to someone in particular, or you want to learn from them and have them help you grow and develop during your time here, you can ask them without having to go through the mentor program thing in NU/W.
