Extension:ThrottleOverride

The ThrottleOverride extensions provides an interface for overriding certain rate limits in MediaWiki for temporary or indefinite amounts of time. Throttle exemptions are applied to IP addresses or IP address ranges, and can affect the page edit, page move, account creation, password recovery, and user email throttles. This is useful if a wiki administrator is expecting and authorizes a large number of edits, account creations, etc. from a single IP address.

Usage
The user-facing part of the extension are the special pages Special:OverrideThrottle and Special:ThrottleOverrideList. On the former, throttles can be overridden and existing throttles can be changed. On the latter, a list of all throttle exemptions that are currently active is shown.
