The "Latest Update" on the front page is dated Sept. 2, 2015.
Which is just announcements and enhancements to the database portion of the site.
The FCC ULS is synced with their database of GMRS licensees weekly.
There's really been no need to update the database side of the site, it runs pretty smoothly. The big shortcoming continues to be the lack of updates from the repeater owners after they initially list their system.
That database should be searchable without logging in, but some of the more detailed info on the repeaters is only visible to registered users.
It is what it is. It's not perfect by any means, but there doesn't seem to be a more useful resource for GMRS out there at the moment. Even if another existed, it too would be dependent on updates from owners or others to be highly accurate. Repeaterbook has some GMRS listings, but they are subject to the same issues.
