I am really interested in making my own Online Game Server but i dont have even a clue how all that works or even what type of server thay are using(i have been hosting a web server before) and i havent even try the original server becouse i have version 2.5 and i dont have money to buy a game on UMD right now so if you have any information about that or if you can give me the source code of the lobby page(i read about it )that you get when you go online gaming it will be wonderful and the link to it so i can try access it through my firefox(browser)

And any other information will be welcome also if you can post screen shot's or give me a link's will be good

Thank you for your help in advance.
