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.
