Where can I (safely) get libintl3.dll?
Turns out I didn't install the setup file with dependencies from this page: http://gnuwin32.sourceforge.net/packages/wget.htm ("Complete package, except sources") Doh!
If you are on Windows 7, you should also take a look at WGet 2 for PowerShell.
The PowerShell version could be a lot more powerful depending on what you want to do with
wget (and avoids the whole DLL install issue, making it more portable)
