slack admin 能做和不能做的事
=========================

為了方便討論 slack 治理機制需要如何限制 admin ，這邊想要條列在技術上 admin 能做到和不能做到的事情，以便知道需要在哪些能做到的事需要多加限制，以及當有人疑慮時，可以用已測試過確認 admin 做不到來做澄清。

本共筆分三區，「才能做」寫 admin 在技術上可以做到的事（但我們治理機制不一定允許 admin 做）、「做不到」寫 admin 在 slack 現有機制做不到，而「疑問」則是放各種還未經證實的，可以請 admin 再測試確認做的到或做不到。

才能做
-----
- 對 slack
- 進行各種設定（可見下面 slack 設定列表）
- 對 user
- 查詢到 user 的 email
- 將 user 停權
- 查到 user 的登入時間、IP 和裝置種類（付費功能）
- 邀請 email 加入 slack
- 建立邀請連結
- 看使用者在哪一天變 active 或 inactive (7天未動作會變 inactive)
- 對頻道
- 修改頻道名稱
- 封存頻道（仍可解除封存）
- 刪除頻道（不留下頻道對話紀錄）
- 對 App
- 安裝/反安裝 App
- 審核是否要安裝 App
- 其他
- 當官方提供 30 天免費 Pro Workspace 時，可以啟用試用
- 匯出所有公開對話紀錄（從2015年開始）

做不到
-----
- 對 user
- 無法修改使用者密碼
- 無法變身成使用者
- 無法得到使用者私訊內容
- 對頻道
- 無法知道有哪些 private 頻道

風險
---
- admin行使權限沒有紀錄
- 其中一個admin可以將其他所有admin剔除（這在大部分的聊天平台都有這類的問題。）-->確保所有對話紀錄都有備份，而且不只單一備份

疑問
----
* Q1: 可否就某先權限對某個admin做限制？
* Q2: 能否將所有的對話紀錄做Backup？

這個表會不會比較清楚？
但可能目前有些設定是跟預設不同？
