MAKE A SCHEDULE. This is particularly important for larger teams.
Figure out who is responsible for handling Piazza on which days. There should be 1 or 2 ISAs monitoring, organizing, and replying to Piazza questions everyday.
Enforce it! Keep each other accountable.
Look for similar questions before answering to ensure consistency and potentially to link to the other question.
Pin important/urgent posts (e.g. assignment FAQs, assignment grades being released, any changes in regularly scheduled activities).
Unpin posts as soon as the information is no longer of vital importance: having too many pinned posts will overwhelm students
Instructions for pinning and unpinning posts https://support.piazza.com/support/solutions/articles/48000616735-pin-a-post
Create a general archive post to put important information posts that are not urgent. Make different categories (recommended: Information + Announcements, Guidelines, Assignments, Tutorials, Assessments, Other). Most recent information should be at the top of each category. Each item should have the title of post, post number @, and date.
Example from Fall 2020:
Be aware when a student has posted anonymously: be careful not to mention them, by name, in your replies.
When you link a student to a post on Piazza that is private, they will not be able to see it by default (unless they made the private post themselves). Be cognizant of this when answering questions.
Students can pin their own posts using the macro.
