A "General" sub-forum would be helpful as I'm not sure there's anywhere else for this post to go:
I've added Widelands to Tiggit, "The Indie Game Installer": http://tiggit.net/

Hey, thanks for the suggestion (and for the kotaku link as well, didn't know about that one.)
Widelands looks really interesting, so I've definitely added it to my to-add list. Since it seems to be updated pretty frequently though, I think I'll wait to add it until our own auto-updater system is finished (which shouldn't be too long.) I'll set up the details once that's done!
