Indeed, thanks for helping! :)

Sure, especially banner building. Multi-lingual sounds good, too.

As a Wikimedia Steward I can confirm that both his accounts are used by the same person who is standing next to me.

A hack in my script should avoid such problems in the future.

Stewards use loginwiki more than 10'000 times per year, see https://meta.wikimedia.org/wiki/Stewards/CheckUser_statistics_for_loginwiki. To date, we need to login to loginwiki to be able to check IPs there with the checkuser tool.

I successfully renamed the account under the auspicies of legoktm.

As AKlapper says, the discussion is about the change which was implemented to send new users and those not logged in to the VE from the search results. However, the underlying issue why this needed to be fixed in the first place is that red links always send users to the wikitext editor. We would like to send users to whichever editor is their default, which currently is only possible for single-edit-tab wikis. Sorry for the confusion.

Hm, afaics, the list stops at G- (see e.g. https://meta.wikimedia.org/w/index.php?title=Special:UsersWhoWillBeRenamed&dir=prev&limit=25 https://de.wikipedia.org/w/index.php?title=Special:UsersWhoWillBeRenamed&dir=prev&limit=25 ). Is there a limit for lists on Special pages that requires extension in order to get more results?

Finally available! :-) Thanks for everyone who made that possible. Will you eventually implement an option where we can filter by editcount or hide at least the 0 edit accounts?
