You dont edit the Master Style. Editing rpg templates in the MS would cause the Revert system (that you can use to undo all edits to a template) to malfunction, plus it will disrupt vB upgrades.
You have to customise all templates on a per-style basis, unless you got Parent styles setup.
And yes, the backend should be working, however if something goes wrong on forumhome, please try searching around in this forum for similar occurrences, and if they are not covered, ask :)

can you take a look at my forum and recommend anything I need to do to more integrate the RPG and make sure that it works?

BTW, how do I initiate a fight with another player? :) I got the drop down menu it looks great!

You enter Battle Arena -> New Battle -> [from here its obvious]
