The Stronghold Kingdoms Website is now accepting further signups from those interested in alpha testing the upcoming MMO version of Firefly's Stronghold strategy series. Word is: "Due to unprecedented demand Firefly Studios are opening up the alpha 4 invites again until the 15th August. Anyone who has registered since the Alpha launched on 19th July will be included automatically (you don't need to register again). This is the last chance to play Stronghold Kingdoms before the beta so get involved!"
