A new domain disputes search engine was just launched. It offers to search ALL major UDRP decisions (except CPR and the late eResolution), plus .uk, .my, .nz or .za decisions.
The webmaster warns: "Since each domain name dispute resolution provider uses different technology and formats to display its complaints, searches can take a few minutes to display a result".
On my first trial, I tried to leave the search field blank, to see if it would indicate the total number of UDRP decisions. Apparently, the tool does not operate a blank search (and does not allow selection of databases).
