In order to better understand Echo usage, and what type of notifications various editors are accustomed to receiving, we'd like to get:
* A list of the 50 **(?)** users who received the most notifications, over the last 90 **(?)** days
* with numbers given for each specific notification-type that they recieved, plus the total.
* (One each for Enwiki, Meta, Commons, Frwiki, Hewiki **(?)** - 5 examples chosen to give a variety of scales, and because certain extensions that use Echo are only actively used at some wikis.)
e.g. 5 tables, with 50 rows each, something like this:
```---------------------------------------------------------------------------
| username | total notifications | mention | edit-user-talk | page-linked | (...)
---------------------------------------------------------------------------
| alice | 987 | 98 | 42 | 2 | (...)
---------------------------------------------------------------------------
| bob | 654 | 76 | 23 | 19 | (...)
---------------------------------------------------------------------------
...```
The complete list of notification types (potentially on these wikis) that we'd like to measure is:
> edit-user-talk, reverted, page-linked, mention, user-rights, pagetriage-mark-as-reviewed, pagetriage-add-maintenance-tag, pagetriage-add-deletion-tag, ep-course-talk-notification, edit-thank, flow-thank, flow-new-topic, flow-post-reply, flow-post-edited, flow-topic-renamed, flow-mention, gather-hide, gather-unhide, gather-approve,
