Traipse Alpha 'OpenRPG' {090924-00} Traipse is a distribution of OpenRPG that is designed to be easy to setup and go. Traipse also makes it easy for developers to work on code without fear of sacrifice. 'Ornery-Orc' continues the trend of 'Grumpy' and adds fixes to the code. 'Ornery-Orc's main goal is to offer more advanced features and enhance the productivity of the user. Update Summary: 00: Update forwards to the 090909-02 Server code that now works. New default Lobby Map, designed for Traipse. Feel free to change it. Updates to Server GUI: * Admin can Ban from Backend. * Prework to modify Ban List in back end. * Server GUI finds your Lobby Name * New users default as Lurker unless a Role is set New Addition to Chat Die Roll commands. Math Ordering. Ex. [(X+Y)dZ]. Currently does pairs only, no nesting either. Cleaner TraipseSuiteAttention portability and clean up in Main (Beta!)
