Everyone's profile includes:
A short bio / "about me"
Your location (used to help others find nearby coaches, sessions, and clubs)
Your DUPR rating, if you have one
Default preferences for self-practice drill sessions — session length and whether you typically play indoor or outdoor
Privacy toggles: whether your profile is public, and whether your drill sessions are shared by default
Whether you want email notifications — see Email notifications: what you'll be notified about
Coaches see a few additional fields that students don't:
Coaching experience
Certifications
Specialties
Focus areas
Filling these in helps students find the right coach and helps your classes and drills show up with useful context attached. You can update any of these at any time from your profile page.
