To upload to SVN:
1) Install Tortoise SVN
http://tortoisesvn.tigris.org/2) Create a new folder, right click it, and select "SVN Checkout..."
3) Enter "https://opensvn.csie.org/osprose/" as the URL of Repository, leave everything else as defaults
4) Select OK and wait, it'll download the latest revision.
5) You will now have the latest SVN release in the folder you created. Now you can edit these files (Or, overwrite them, if you're sure you won't delete anyone elses work)
6) To upload your changes, right click the folder and select "SVN Commit", make sure to enter a list of what you've changed so we can keep track. It will then ask for a username/password, ask pepu to create an SVN account for you, or use the supplied user/password given to all devs to access the opensvn page and make your own.
