**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 and measurements:**
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/week
* The restriction only applies to the main namespace, therefore, edits in Talk namespace are expected to increase
* If the restriction has a deterrent effect, total edits across all namespaces may decline
A series of metrics were used in the [[https://meta.wikimedia.org/wiki/IP_Editing:_Privacy_Enhancement_and_Abuse_Mitigation/Impact_report_for_Login_Required_Experiment_on_Portuguese_Wikipedia|past experience on ptwiki]]; these were all trended overtime with a monthly bandwidth:
* Number of new accounts
* Number of active user editors
* Retention rate
* Number of edits
* Number of reverts
* Number of net non-reverted edits
* Number of net non-reverted content edits
* Number of blocks
* Number of protected pages
* Number of CheckUser requests
Qualitative measurements were informally done in the ptwiki experience. It may be worthwhile to solicit feedback from the users more formally, both during and after the temporary restriction.
**Done**
