RFCA (RFC of Asia) is another mod where I'm involved in. It's also working on Sourceforge. I want to upload a new version of it. IIRC, it works the same as releasing a new Beta for RFCE, but I don't know how that works.
When I want to get a new version, I make sure the SVN is updated, then I have a command to "export" the solution, which strips all of the svn information and creates an RFCEurope folder. Then I zip the folder and upload it to the files section of sourceforge. Once the file is uploaded, you need to set it as the default upload. However, you can only do that if you are an "administrator" in the svn project, for RFCE it is you, me and sedna17, I don't know about RFCA.
In your case, you need to find the "export" command in the SVN client that you are using (i.e. tortoise SVN).
