Teacher/Tutor Role Icon
Teachers play teaching games, review games, explain things, contribute tsumego and other content material and so forth.
For the average player, it would be helpful to identify teachers. One may approach them with a question or a review request.
I propose, based on the discussion in https://forums.online-go.com/t/accessible-teaching/11039, to introduce the distinction of “teacher” for users. This property would be indicated by a small icon next to the user name and a notice on the profile, similar to site supporters and moderators.
The title of teacher can be gifted by any user to any other, but also suppressed or turned down by oneself as well as taken away by a moderator. Other ideas on how to curate teachers are discussed in the linked forum thread.
It will be important to distinguish between professional teachers who offer services for payment and volunteers.

The above link shows an example of a what the hat can look like. Perhaps a gold tag, or change of color can ID teachers.
