The one you linked to isn't compatible with the current version of SMF, but this one probably is:
http://custom.simplemachines.org/mods/index.php?mod=195The problem is that when I upload it, SMF reports the archive as corrupt. So does WinRAR when opening it, although WinRAR is able to extract what looks like all the files.
In the support thread, a user asked about this, but another user just chided the first user for not reading a supposed forum announcement explaining the cause...said announcement being nowhere to be found. Furthermore, apparently the rules of the mod site don't allow anybody else to fix the problem and upload it, and the original author has disappeared.
So if anybody can somehow re-package and fix this, and unless there are any other unforeseen problems, I'll install it. I tried just re-creating a .tar.gz out of the same files, but SMF still reported it was corrupt. Otherwise, I'll check back at the site periodically to see if the issue has been fixed.
