We should log some data about `Special:Mute` usage. This will be helpful for us to determine how the mute features are used currently and provide a good indicator for whether merging the mute lists is a good idea.
Here are some things that would be good to learn:
* **How often do users land on this page and from where?** Email, user pages, echo notifications etc. It will help us see what is the best place for users to find this page.
* **Of the users who land on this page, what percentage of users actually mute someone?** This will let us see if the page itself needs improvements - is the page intuitive enough for people to know what to do or are we scaring away users?
* **Of the users who mute a user, which option(s) did they check in order to mute the user?** This will be a good way to validate our idea of merging the two mute lists. If people check only one option and not both, then we know there is a real use case of only muting users on one venue but not the other(s).
