The Swedish Skeptics have agreed to re-test Ms. Landin's claims, with the help of the JREF to provide a protocol.
Ms. Landin has suggested using rings as her target items. Unfortunately, the rings would have to be known to have been worn often by their owners.
We have begun correspondence with Ms. Landin regarding a possible re-run of the diary test involving more diaries of the time period she specified.
If Ms. Landin agrees to using diaries again, we will be on the lookout for diaries. If you have one, or know someone who does, please seek them out and stand by for more information.
