@creepyyodasoda I just added Project Pluto to the server monitor at the bottom of this page (and all pages on this site). It will let you know when the server as up. When servers are online, you can click on them to access their dedicated webpages.
Any full client, such as Nexus 2 or the BlastClient, should work. There is no functional difference, although Nexus 2 is larger because when it was first uploaded (a long time ago), we accidentally included some duplicate sound files that are unnecessary.
