[Resolved] Lonely challenges

General question here. I notice that in the "Read Me First" post of March 2017 it says,

"The checker does not have access to logs from others on the geocaches logged. Therefore a challenge to log a geocaches that hasn't been logged for one year isn't possible. We are however looking into solving this in the near future (June is expected). Details are yet to be determined."

Has this been resolved? Are lonely cache challenges now available?

Thank you,

This is still not possible but there is a PGC alternative

That is:
Loneliness is defines as age/(number of finds)
The age is the number of days between hidden date and today's date if it is an active cache.
For an archived cache it is days between hidden and archived.
Your finds on archived caches after the achiving date are not included.

Thank you. One of my group wondered about a lonely fizzy challenge. I didn't think it was possible, but that "June (2017) is expected" comment got our hopes up.
