I know this isn't the support forums for the site, but the Mod Author has been gone for far too long on his own site. I am running a site with a friend, www.southwestracingscene.com and we're running the PhpBB Garage 1.2.0 Beta 4 on it, however due to a hosting change, some of the files became corrupt. To top that off (I keep backups on my computer) my laptop hard drive failed on me as well, so I lost the only complete Garage 1.2.0 Beta 4 that I had.
If the admin here has it in a zip form, can you PLEASE send it to me? I can set up a FTP just for you if you don't want to waste bandwidth.
Very nice looking site here too.
