A few month ago Frank Schulenburg asked me if it would be possible to exempt single IP addresses from the account creation throttle. He filed https://bugzilla.wikimedia.org/show_bug.cgi?id=25000
Besides the existing way of defining an exempt in the config files I hacked a bit and committed http://www.mediawiki.org/wiki/Special:Code/MediaWiki/72959
An easy way, a bit too easy: it was reverted *hides*.
Now he asked me again on Wikimania what to do because he will need in the future more exempts for bigger groups. All known ways seem not very nice:
* Account creation by admin does not scale for > 100 new accounts * Edit the config file is restricted to sysadmins
I think about writing an extension with a special page where admins can define IP address, start and end time of the throttle exempt.
What do you think? Have I missed an easier way to approach his needs?
