Questions, answered
Will it post to Instagram without my approval?
No. Every post is a draft that lands in Slack first. You read the caption, adjust if needed, and publish it yourself.
How does it decide a class is under-booked?
By default, any class below 50% capacity triggers a draft. You can raise or lower that threshold - for instance, only promote classes with 3 or fewer spots filled.
Can it handle multiple class types in one post?
Yes. If several under-booked classes fall at similar times, WebRun can draft a single carousel-style post listing them all rather than flooding your feed with separate posts.
