A forum has been set up for the Sylverant project, both its open-source project and this private server itself at DCEmulation.org. See the link in the navigation bar at the top of the page, or click this link to get to it.
You might find yourself asking why would I choose to make the forum for Sylverant at DCEmu? Well, the first and most obvious reason is that PSO is of course a Dreamcast game. Second of all, I’ve been a member of the staff there at DCEmu for a long while. Anyway, feel free to use that forum to discuss anything that you wish with regard to Sylverant, as long as it is within the rules posted there. Enjoy!
