There's a recurring issue when people do outreach events for potential Wikipedia editors: Such events are often done in a library or a school, which uses the same IP or a small IP range, and because of this after a few people create an account, further account creation is throttled.

The page
https://www.mediawiki.org/wiki/Help:Mass_account_creation
offers some way to overcome this, but they are not very convenient. They either require the accounts to be created up front, or to have them created by a sysop, which misses the point of teaching people how to create accounts.

The limitations can be lifted by asking cluster sysadmins on IRC to lift the restrictions by doing configuration hacks, but this is very inconvenient for most people and it is error-prone, too.

What is needed is a system that would let somebody with permissions (probably a bureaucrat or a steward) to allow unlimited account creation from a range of IPs in a given time range.
