I\'m new to both Sourceforge and SVN (SilkSVN on Windows).
I managed to check out a project using
svn co --username=zeroth123 svn://zeroth123@svn.code.sf
For anybody (like me) working with Tortoise SVN who has it working for Tortoise SVN but needs command line access for easier bulk analysis... and doesn't want to go through the faff of registering an SSH key.
That way, you can use the Tortoise Plink.exe with arguments for username and password.
