For the Scholar hat icon:
I think it would be based on the mods and owner of OGS to decide on this.
In my opinion the Qualifications would be:
- Users Providing scheduled learning per days; (ie 1 scheduled learning per 90 days)
- Actively teaching / looking for students.
- Are open to being asked for reviews.
- Are Actively creating, updating or improving Accessible learning;
4.1) Active Creators of new quality Tsumego Packages.
4.2) Content Material providers; Such as Francisa providing 81 little lions for OGS use.(( 81 Little Lions - An introduction to the 9x9 board for advanced beginners )) - Special case users, such as users facilitating scheduling learning (Finding games games for review, assisting with creating lectures or lessons) or being a point of contact for mods and scholars.
