**Motivation:**
Farsi Wikipedia is implementing a change that would disallow IP editors from editing the main namespace. We should capture metrics to assess the impact of this change on the project's health, similar to ptwiki metrics.

**Proposed metrics:**
A series of metrics were proposed by the fawiki community. Some have been implemented as SQL queries by @Jeeputer and the queries and latest results can be found on [[https://fa.wikipedia.org/wiki/%DA%A9%D8%A7%D8%B1%D8%A8%D8%B1:Jeeputer/%D9%BE%D8%B1%D8%B3%D9%85%D8%A7%D9%86%E2%80%8C%D9%87%D8%A7|this page]]. Also note that some of the metric definitions may need to mature more e.g. be time dependent (e.g. "within X days") and some include definitions (e.g. "newly registered users") that have to be carefully crafted into SQL queries using a mixture of features such as registration date, number of prior edits //until a specific edit//, etc.
* Proportion of all IP edits that have been patrolled within X days
* Number of edits by newly registered users
* Total edits per namespace per day
* The restriction only applies to the main namespace, therefore, edits in Talk namespace are expected to increase
* If the restriction has a deterent effect, total edits across all namespaces may decline
