I'm no expert on this and have not yet done it but from what I've seen people used to create a project on SourceForge until it fell into disfavor and now they are putting it on GitHub. I also have a project which I would like to open source and have been debating where I should put it. It is a processor design so I also have the option of putting it on OpenCores. I would be interested in hearing recommendations about where I should put it.
