It wouldn't have to be just for tutoring, but it can help in terms of mentorship and just learning from older people with more real life experience and career.
Other thoughts: - I thought the signup buttons/some action buttons could use a color contrast - some of them were hard to see visually. - Some of the visual indicators when the mouse hovers over a button/action would be nice, just so the user knows which items are more clickable - more affordances can be nice. - I put in my preferred name to be called during sign up.IF you are going to do verification, maybe you can make that clear. Or have the option to keep a nickname. - The profile page needs more information for editing and display. But I think it is probably on your backlog.
