formatter URL (P1630) is missing and the link in the documentation points to "page not found". Matěj Suchánek (talk) 10:57, 16 January 2016 (UTC)[reply]

There seem to be no direct link to http://ukmoths.org.uk using the BF identifier itself. I added a formatter URL (P1630) leading to a site search, but it actually brings a list of search matches that may be pretty bad. At the end I defaulted to a direct link that uses an independent search engine, DuckDuckGo in this case: https://duckduckgo.com/?q=!ducky+BF$1+site%3Aukmoths.org.uk. -- LaddΩ chat ;) 16:31, 17 January 2016 (UTC)[reply]

@Pigsonthewing, Matěj Suchánek, Laddo: Hello. The formatter URL is not working anymore when used on UKMoths. What about having a new property for that website only now? Thierry Caro (talk) 02:15, 10 November 2018 (UTC)[reply]

Agreed, that site now seems to use names. --99of9 (talk) 12:08, 29 July 2020 (UTC)[reply]
