Just curious if the mozilla based browser will grace the UIs of the Forgelight games or not, because I find/found it handy in EQII and SWG. Sure, you could use windowed mode or alt-tab to look something up, but it's so much nicer to stay in the game and have that information as part of the UI.
One thing it would be really good for is organizing events for your outfit, by using a simple forum/calender website inside the actual web browser. All SOE would really need to do is make it easy for a person to set a url as their homepage, by perhaps adding a "set as homepage" button on the browser button bar. The fan sites could do the rest of the work to blend their sites into the UI of the game's browser, such that the sites would simply look like they are actually part of the game.
Anyhow, it's such a mundane feature of SOE games (much like cross game chat), yet it's so unique and full of potential at the same time that it would almost be a shame to omit it. That said, it may well be just another thing for hackers to find a hole in...
